Science in a Troubling Political Climate – Dr. Chris Widga – Part 2

New Hampshire doesn’t have a state museum.  I never realized there were such things until someone I interviewed mentioned a mastodon fossil in Albany, which prompted me to travel to the NY State Museum soon after to see it.

Not understanding what a state museum is, it shocked me that there was no admission fee; anyone from anywhere could visit the museum at no cost.  I marveled then—as I marvel still—that such places exist. (To be clear: not all state museums are free.)

Illinois not only has a state museum, that museum is made up of five separate museums with over 13 million artifacts.  And in 2015, Governor Bruce Rauner wanted to close it completely.

During a messy and contentious budget battle, the museum was shuttered for nine months, only to be reopened this past July with a new $5 admission fee.  But by then, most of the staff had gone, forced to take jobs in other places as their future at the museum was decidedly uncertain.

No one knows this better than Dr. Chris Widga, who had been a vertebrate paleontologist employed at the Illinois State Museum.  He now works at the Center for Excellence in Paleontology at East Tennessee State University (ETSU).

“The whole question of Channel Islands and island mammoths probably got me through last winter,” Dr. Widga explained as we spoke by phone.

We were discussing the effect islands had on proboscidean evolution and the exciting recent research done in part by researchers from The Mammoth Site and the National Park Service.

“In Illinois, as the State government was falling apart around my ears, as the State Museum was closed, I basically closed my door and was doing the analysis for the Quaternary International article. In so doing, I was thinking about these pygmy mammoths. As it’s icy outside and subzero for about six weeks at a time, that kept my sanity.” He laughed.  “So the Channel Islands has been my refuge, I guess, even though I’ve never actually been out on one of them.”

The move from Illinois to Tennessee was not just a contrast in physical environments.  It also meant moving from a scientific institution founded in 1855 to one that has been open for just 10 years.  Dr. Widga explained that a mere two weeks prior to his start date at ETSU, the university formed a partnership with a local science center.   The ETSU staff maintains the collections, conducts research, and oversees excavations at the nearby Gray Fossil Site.  The science center staff is responsible for educational activities within the museum and overall maintenance.

“Their [educational] philosophy is very similar to ours,” Dr. Widga said of the science center. “It’s inquiry-based. We want people to come in and learn through asking questions rather than just be spoon-fed facts.”

So much of what Dr. Widga has done involves public outreach.  From videos about the collections at the Illinois State Museum to long-distance learning programs like The Mammoth Expedition, work he did in conjunction with Dr. Katy Smith at Georgia Southern University and with the Milwaukee Public Museum.

When I commented on how much I loved that kind of publicly accessible information, his response was, “Part of that is because I’m in a museum. I’m not buried under coursework and teaching. Outreach is valued. The way you justify your existence in a museum is to connect with the public.  And part of that is figuring out how we can connect with the public in ways where it’s an exponential relationship.”

In other words, not having a one-on-one conversation with a museum visitor, but creating a website about the Ice Age in the Midwest, for example.

Despite everything he’s gone through, there is no question Dr. Widga loves what he does.  It permeates his voice when he speaks of paleontology, and it prompted me to ask if he ever becomes excited at work.  His response was a definitive ‘YES.’

By way of explanation, he quoted his now-retired colleague, Dr. Jeff Saunders, who used to say, “‘Going to work in the morning was like going to Disney Land everyday.’”

Not only did the two scientists literally work across the hall from each other at the Illinois State Museum, they were apparently known to shout out excitedly to the other whenever one read a great article or wanted to share a relevant scientific image.

“Part of the reason I like museums is because you just never know!” Dr. Widga continued. “Some of the new things come from the collections; some of the new things come from new papers. You read them and you’re like, ‘oh, this explains it!’ It was something that you had been working on for a long time and, all of a sudden, somebody else had that last piece of the puzzle that puts the whole thing together.

“At least once a day—even on the worst days—there’s something that comes through and I’m like, ‘oh, this is so cool!’”

The seemingly idyllic work environment in Illinois lasted for a decade until 2015. Despite protests, a MoveOn.org petition and public outcry about the museum closing, Dr. Widga and his colleagues were forced to consider other options.  The fate of the museum was out of their hands.

“There was a point as I started looking for jobs last year that I asked myself, you know, do I want to continue in this vein?”

“I’d watched many of [my colleagues] that had taken jobs in Research One institutions [become] totally burned out.  Or they’d kind of gone in weird and funky directions, not because the research was taking them in that direction, but because they were getting pressure from their institution to go in a certain direction or something like that.

“And that was part of the fun of the Illinois State Museum is that I could work on anything. Nobody was saying, ‘You have to work on elephants.’ That was a choice that was mine. Nobody was saying, ‘well, you have to work on dogs.’ That was a choice that was mine. You could chase whatever questions were out there.

“The feedback that I got from the people that interviewed me [was that] they were very interested in what I did.  It was a very different situation than what we were going through at the Illinois State Museum where, essentially, you were being told, ‘what you do is not important.  And none of what you do—your position, your entire existence—is important.’ [The feedback I got while interviewing for other jobs] revived this idea that what we do is important, and it’s exciting.”

I couldn’t help but compare his experience in Illinois to the general anti-science climate in our government today.  It was particularly interesting for me to speak with Dr. Widga about his paper on Pleistocene ecology a day or so after the House Science Committee’s so-called hearing on climate change.  Dr. Widga’s infectious enthusiasm took a very somber turn, as he conceded how difficult things become when “politics starts really driving the boat and reason takes a back seat.”

“That won’t change any of the science,” he added, “[but] it may change how the science is funded. It also won’t change any outreach that we do or the educational activities! In fact, if anything, it’s going to make those seem more important and put more emphasis on those.

“We can talk about the scientific community writ-large, but certainly within the paleontological community, you will find very few working paleontologists, working scientists, who say that education and outreach is not a good thing anymore.

“It used to be that you could just hole-up and do your research and never really interact with the public.  But if anything, this whole process [with the IL governor and the Illinois State Museum] has made us realize that that can’t happen.

“There’s this realization that pre-dates this modern political atmosphere: That you really do need to work with the public and you need to make sure that the point of what you’re doing is out there. Not just in terms of dinosaurs are always cool so therefore that’s why we’re doing it. But we’re also doing it to learn more about how our world works–the nuts-and-bolts of how ecosystems are put together, the nuts-and-bolts of how climate changes impact those ecosystems–that has real-life implications for today and into the future.

“And there’ve been some really loud voices in the last couple of years that have said that over and over and over again. Some of which are people like Jacquelyn Gill! And that is a big shift in science. It’s a big shift in science communications.

“I’m glad that we were moving on that before the current [political] atmosphere because it makes it much more difficult to sideline us as, you know, a bunch of eggheads.”

It didn’t take long for our conversation to take a positive swing upward, as Dr. Widga then described possible future projects involving scientists across the country.

His statement “I’ve always been of the opinion that science is a collaborative effort” couldn’t be more apt.  And I, for one, cannot wait to see what he and his colleagues work on next.

North American Proboscideans and Dr. Chris Widga – Part 1

“Most zooarchaeologists are interested in the people, and they use the animals as kind of a tool for understanding butchering patterns or food ways or something like that.”

Dr. Chris Widga and I were in the midst of a great conversation about three recent papers he co-authored, paleontology, proboscideans, and the state of science today.

“I was always interested in the animals themselves,” he continued, “so when I got the position as a vertebrate paleontologist at the [Illinois State Museum], all of my friends who’d known me for years said, ‘well, that was a no-brainer for us. You were doing vertebrate paleontology all the time on Holocene bison. You never cared much about the people!’”

That beginning in zooarchaeology and the subsequent immersion in paleontology are what give him a unique perspective of the two sciences.  Or, as he himself explained: “I guess I kind of have this foot in both worlds.”

The two occasionally overlap.  In the paper published this past February in Boreas, “Late Pleistocene proboscidean population dynamics in the North American Midcontinent,” he and his colleagues take a closer look at what might have caused the extinction of mammoths and mastodons in what is now the middle of North America. Possible culprits include climate change, shifts in available vegetation, and predators (including humans).

Of the 627 localities included in this study, only 3 offer any kind of human association.  The authors state that these sites were “re-visited to ensure consistent taphonomic and zooarchaeological data,” and that, despite this, whether or not these specific humans and proboscideans interacted remains unclear.

“That’s a distinction I like to make as a paleontologist and a zooarchaeologist,” Dr. Widga offered. “Just because we have a couple of the sites with humans associated [doesn’t necessarily indicate that] humans actually hunted, killed and butchered those animals.  [Humans] may have scavenged them.  They may just simply be associated in these sites. And very few of those sites have been analyzed to the degree of detail that we really need to start teasing apart those issues.”

What he and co-authors Stacey N. Lengyel, Jeff Saunders, Gregory Hodgins, J. Douglas Walker, and Alan D. Wanamaker try to do, however, is take a deeper look at the late Pleistocene environment in which these proboscideans lived.  It’s exciting research: Rather than simply describing fossils discovered in the various US states and one Canadian province, they are trying to put them into context.  In other words, they are trying to understand the ecology of that time period and how that may have affected the megafauna living within it.

But it’s not an easy task.

“Ecologists can look at modern ecosystems and say, ‘Ok. This is what’s going on, and this is why we think that, and this is how we’re measuring it’ in great detail.  But extrapolating those same processes back into the paleontological record is often really, really difficult even with the best data set.

For example, “[w]e can observe boom-and-bust cycles in deer populations, in caribou populations, in musk ox and things like that. But when you try and translate that into the paleontological record, most of the time it’s really difficult because you simply don’t have the samples and you don’t have the time resolution.

“Even in our case, where we have really good samples and we have really good dates on our samples and we’re creating this chronological structure to kind of fit them in, it’s really difficult to translate those patterns into ecology.

“We can’t date a single mastodon any more precisely than about a hundred-year window.”

The fact that some of the ecological constructs used today in extant populations are controversial makes trying to apply such constructs to extinct animals that much more of a challenge.

“When even the ecologists can’t truly [agree upon] what’s going on, you have to navigate things very, very carefully.”

The amount of work put into this paper (work that has produced previous, subsequent and yet-to-be-published papers) is staggering.  Thanks to a National Science Foundation grant, Dr. Widga and Dr. Jeff Saunders—both previously at the Illinois State Museum—were able to visit an astounding number of museum collections in the Midwest and review their proboscidean fossils.

“We’ve [basically] spent the last 5 years in other people’s collections,” he explained. “It was fun because we visited a lot of collections that people don’t usually go to. About half of the data set comes from repositories that have fewer than five mammoths and mastodons.”

Their work involved the review of over 1600 fossils that currently reside in collections in Ontario, Canada, as well as in Arkansas, Illinois, Indiana, Iowa, Kansas, Kentucky, Minnesota, Michigan, Nevada, Ohio, South Dakota and Wisconsin.

“We doubled the number of known published sites for mammoths and mastodons in the Midwest.”

Information that they are willing to share with other scientists, as evidenced by the number of papers they continue to co-author.  Following the Boreas paper, Dr. Widga was part of another two papers published in March in Quaternary International and then in Scientific Reports.

Mammoth teeth take a leading role in the paper, “Reconciling phylogenetic and morphological trends in North American Mammuthus,” published in Quaternary International and co-written with Jeff Saunders and Jacob Enk.

“We’re starting to put out some of these ideas that actually put data onto these [traditional] species boxes that we like to put specimens into.  So that was one of the first steps into thinking about these things: more as morphologically variable populations rather than just trying to assign them to a particular species.

“A lot of times these studies kind of happen in isolation.  So the people that think about morphology, they’ll publish on the morphology and then post-hoc, they’ll say, ‘oh but this doesn’t agree with the genetics at all.’ Or the geneticists will publish on the genetics, but they don’t integrate any morphology.  So our point was to try and integrate both of them and see what they say. Can you use the genetics to kind of structure your interpretations of what the morphology means?”

The authors studied “M3s”—the permanent upper 3^rd molar—of both female and male mammoths of various ages from museum collections and from previously published work.

Per Dr. Widga, this is the upper 3rd mammoth molar from Clear Lake Sand and Gravel Pit, Sangamon County, IL. One of his favorites from the ISM collection. It dates to the Last Glacial Maximum and had preserved DNA so is included in the Enk dataset; image and caption courtesy Chris Widga.

 

“Jeff [Saunders] and I would say, ‘this genetic information actually fits perfectly with our morphological information which suggests that there’s a lot of population overlap in between these normally well-defined populations.’ So in between Columbian mammoths in the Great Plains and woolly mammoths from the Great Lakes you have Iowa mammoths that show characteristics of both. And also they show characteristics of both in the same animal!

“That was kind of the impetus for the [Quaternary International paper]: to get that out there, show that you do get a lot of overlap in the morphology. It’s not just clean boxes of Columbian mammoths and woolly mammoths. And even pygmy mammoths overlap with Western Columbian mammoths! So that was kind of the point of the paper: to get the conversation going and make a first pass–a first attempt–to reconcile the two data sets.”

Following soon after the paper in Quaternary International, he was part of a remarkable group of proboscidean and genetic scientists whose paper The evolutionary and phylogeographic history of woolly mammoths: a comprehensive mitogenomic analysis analyzed 143 woolly mammoth mitochondrial genomes.

As Dr. Widga said with characteristic enthusiasm about his work in paleontology, “It’s always fun! There’s always a mountain to climb and a vista to see!”

A Mammuthus columbi-sized THANK YOU to Dr. Chris Widga, who was remarkably generous with his time, with images to use and with answering my many, many questions (both for this blog and for my own proboscidean curiosity).  Speaking with him was delightful; he is an incredible ambassador for science in general!

Another sincere THANK YOU to Ron Richards for providing the great images of the Indiana State Museum collection.

Rewriting the Story of How They Died – Columbian Mammoths in Waco

[[The following text has been edited from the original post.  Email me for the original post: mostlymammoths (at) gmail.com or read the full scientific paper by the authors here.]]

*****

Sometimes, it just takes a different point of view.

The largest known potential nursery herd of Columbian mammoth fossils in the world exists in Waco, Texas.  Of the 25 mammoth skeletons found to-date, 16-22 of them died at the same time. Something catastrophic occurred to these animals in the Pleistocene, but just what remains inconclusive.

While some speculate death by lightning, disease or miring, the predominant theory maintains that this is a herd of mammoths that died and were buried in the same flash flood.  It’s an idea that has stuck for many years given the existence of aquatic fauna and the evidence of an ancient river upon which many of the fossils have been found.

But Logan Wiest, Don Esker and Steven Driese of Baylor University have a different hypothesis, one published this past December in Palaios.  By studying traces on the bones available in situ, as well as those available in the nearby Mayborn Museum, they offer an entirely new idea: water didn’t kill them; its absence did.  Struggling to find water in a drought, these animals may have collapsed and died at a watering hole that could no longer sustain them or anything else.

Columbian mammoths were enormous animals.  In general, they are known to be much larger than woolly mammoths and considerably larger than mastodons, both of which were behemoths in their own right.

The mammoth skeletons at Waco are thought to be a matriarchal herd, consisting mainly of females and youth (no calves).  The evidence suggests a herd, and there is more research to be done to prove it using stable isotopes.  A single bull has been discovered in a different geologic layer.  Separate fossils of other species—none of them complete except for a western camel—have also been found throughout the site.

Don admitted he didn’t have an alternative explanation for the death of so many animals. He invited his colleague, Logan Wiest, to take a closer look at the fossil evidence.

“I’d brought [Logan] in hoping he’d look at the [site’s paleosols],” Don said. “I knew he was a trace fossil expert, so I’d hoped he [might] tell me a little bit about the conditions based on worm burrows, [for example].

“What he found instead was much more interesting! He found that there were all kinds of bite marks on the bones.  We didn’t find those all at once.  It actually took quite a while [before] we recognized what we were seeing as bite marks.  A lot of literature research and a lot of staring at bones.  Those bite marks shouldn’t have been there if the mammoths were immediately buried.

“One of the first things he noticed and was able to identify quickly were dermestid beetle bite marks: pits that the beetles dig in the bones when they’re going to lay eggs.

“I thought that perhaps [evidence of dermestid beetles] might be there, but I didn’t realize the significance of [that evidence].  He’s more of an expert on this than I am.

“And he knew that dermestid beetles don’t eat wet meat.  It actually has to be almost completely dessicated–no moisture left at all, just the fats and proteins–before the dermestid beetles will touch it. And that didn’t fit well with animals that were killed in a flood and rapidly buried.

“Dermestid beetles also don’t burrow. Even a single inch of soil is enough to keep dermestid beetles from digging down to perfectly good meat.  They can’t dig.”

“So, it was Logan looking at this and trying to think about what might be causing this instead of a flood, and he said, ‘Well, how about a drought?’

“I knew about some other evidence that really fit with that. So that clicked with me very quickly, particularly the fact that we’ve got both aquatic and terrestrial animals—a great diversity of them all in the same place.  What that suggested to me was a diminishing watering hole. And I wouldn’t have realized that if Logan hadn’t noticed the dermestids and figured out the drought angle.”

Beyond studying the available literature for trace fossil search images, they tested their ideas on the heads of deceased wild hogs using extant dermestid beetles. In effect: they put the fleshy heads into a contained area and let loose the beetles, who proceeded to consume all of the flesh, leaving clean skulls. It’s an efficient and chemical-free method used by scientists and museums the world over.  But for Logan, Dan and Steven, this provided more data for comparison. Traces left by the beetles on the wild hog skulls are similar to traces on the fossils in Waco.

“Previous studies have attributed trace fossils of this size and morphology to dermestid beetles,” Logan wrote in response to what prompted them–of all insects that might have left traces on fossils–to think of dermestid beetles.  “We simply wanted to test this notion by providing bone to dermestid beetles and seeing if these traces could be duplicated under controlled conditions. The beetles came from a nearby museum, but they are also native to Texas. We used the head from a hog simply because wild hogs are easily accessible in central Texas.”

A true ichnologist, Logan added, “I’ve also spent a great deal of time observing bones of modern cattle that were scavenged upon in pastures near my home.”

They didn’t just find evidence of ancient dermestid beetle traces; they found traces of animals who gnawed at the bones: rodents and carnivores, including a possible saber-toothed cat.  It is important to consider that animals drowned and then rapidly buried in a flash flood would not be accessible to these terrestrial scavengers.  This indicates that these Columbian mammoth carcasses were exposed on land long enough to be at least partially devoured.

That, too, is key. Remember that most of these mammoth fossils are articulated skeletons, complete except for missing tails and parts of their feet.  In an area devastated by drought, even scavengers would lack the energy to completely devour and tear apart a carcass.  All of these clues add more weight to the scenario proposed by these authors.

Describing the tools they used to study the fossils in situ, Logan wrote, “The low-angle light creates a shadow which makes the small structures on the bone surface to be easier to see and photograph. We used a Dino-Lite portable microscope to study the fossils mainly because we are unable to transport the mammoth remains from the site to the laboratory. Studying the fossils in place is the best way to ensure preservation of the original positions.”

In other words, because the fossils remain where they were found, they studied those available directly at the site.  Their paper states that the in situ fossils comprise 30% of the available Waco fossils.  The rest reside at the Mayborn Museum, some of which are available in their collections, but most of which remain unopened in their plaster jackets.

“It’s an amazing site,” Don enthused, “and there’s decades and decades of research there, on top of potentially a lot more excavation, too, because they are in NO WAY finished excavating. What they’ve got probably represents a fairly small fraction of the whole deposit.

“One of the things that Logan and I were speculating about [is] if you’ve got a really big regional drought, that should show up in multiple places in the geologic record, especially right in that area.  The bed that we’ve got marking the drought as this depositional hiatus could be covered with bones for acres and acres in every direction.

“And we know that it’s covered in bones at least 80 or 90 feet away from where the known deposits are because we’ve done core sampling that have pulled out large bone fragments.  We only did a couple of them—a couple at random!—and they hit bones both times.”

The Waco Mammoth site itself has been around for 39 years, but it has only been part of the National Park Service since July 2015, thanks to President Barack Obama and the work of many people years beforehand who helped bring that to fruition.  Don and I discussed this by phone, given the current political climate and the fears that some National Monuments might lose their status.

“That’s really worrisome,” he remarked. “And what really sticks in my craw about the Waco Monument in particular is that it’s costing the Federal Government almost nothing.  The city of Waco is paying for almost all of the upkeep.  The original buildings? That wasn’t tax money. That was done by good old fashioned fund-raising. And the day-to-day operations are almost all city.  There are a couple of rangers there alongside city employees and some signage and brochures. And that’s really all the Federal Government’s paying into it.”

“It’s a really incredible place.  There are not a lot of sites like this anywhere, as far as in situ fossils sites go.”

Eliann Stoffel – Unlocking the Secrets of a Forgotten Mammoth

A rather large bone, revealed by his bulldozer, prompted William McEvoy and his crew to cease work on the road and call the police. The police then called the local archaeological society, who, in turn, called an archaeologist at the local Natural History Museum.

When word got out that a mammoth had been discovered, visitors began pouring in to see the site.  Just a few miles outside of the town of Kyle in Saskatchewan, Canada, the excavation of these fragile bones from the hard clay was witnessed by an ever-growing number of people.  It is estimated that 20,000 visitors came to see the site that autumn in 1964.

Eventually, the plaster casts protecting the bones were taken to the Natural History Museum (now known as the Royal Saskatchewan Museum); radiocarbon dating was conducted.  Possible museum displays and skeletal reconstructions were discussed.

And then?

Nothing.

Once the cause of great local excitement, the bones of the Kyle Mammoth faded from view.

The references above to archaeology are not errors.  Although the bones found were paleontological in nature, the focus on the find—and, indeed, the very reason they were recently resurrected—was to determine whether there was any evidence of human-proboscidean interaction.  When no stone tools were recovered in the surrounding sediment and with no obvious signs of butchering on the bones, interest in the fossil seems to have collectively disappeared.  For over 50 years, the various bones found on that stretch of road have been shelved in the Museum’s collections.

“I had always planned on doing my thesis at the University of Saskatchewan and I knew I wanted to do my thesis on hunting and butchering strategies utilized by Paleoindian people,” explained Eliann Stoffel, a recent graduate, in an email.

Her interest was not specific to any one species of megafauna. She hoped to study any and all large animals ancient people may have hunted: camels, bison, horse, proboscidea.

“I had approached my supervisor, Dr. Ernie Walker, with this topic and he had spoken with a member of the Saskatchewan Archaeological Society, Frank McDougal, who had suggested taking a look at the Kyle Mammoth.”

Which is how the long-forgotten fossil came back into view in 2015.

“We knew that the mammoth belonged to a time when people were in North America and actively hunting mammoths so we had the possibility of finding some sort of evidence of humans on the Kyle mammoth.”

This evidence is rare in the area known as the Northern Great Plains, an area that encompasses Saskatchewan (as well as another Canadian province and five U.S. states).

“It was one of those projects,” she said later by phone, “that, as soon as it came up, I couldn’t turn it down.  It needed to be done.”

Travelling between Saskatoon and Regina (where the Royal Saskatchewan Museum and the fossil are located), Eliann spent many hours studying and analyzing the bones from the 1964 excavation.  This included five boxes of bone fragments as well as 56 complete or near-complete bones, such as vertebrae, mandible, a partial tusk, and ribs.  Also included were ungulate bones, which—like the mammoth—did not comprise a full skeleton and did not present any clear association with its proboscidean fossil companion.

Eliann’s thesis presents a comprehensive taphonomic analysis of the mammoth bones, and this was done because she and her advisors “knew that we needed to keep in mind that we might not find any evidence of human involvement.”

The idea of determining who or what made any kind of marks on a fossil seems like an overwhelming challenge.  This was not an animal that died the other day.  In this case, it died roughly 12,000 years ago. That is a considerable amount of time in which—after an animal is butchered, killed or otherwise dies of natural causes–it can be scavenged after death, it can be moved and scraped by natural elements, it can be affected by its fossilization, and then possibly affected by the process of discovery (in this case, by a bulldozer). How is anyone able to read the marks on fossil bones and know what they represent?

“[T]he first giveaway is the colour,” she wrote. “Bone, when it has been buried for a long time, tends to become stained from the surrounding sediment but only the outer surface. So when someone (an excavator) knicks the bone, the unstained inner portion of the bone is exposed and tends to be a lighter colour.

“The other indicator can be the clustering of marks. [With] butchering, there tends to be more than one cut mark on the bone in the same general area, usually at muscle attachment sites, and they tend to be orientated in the same direction. Rarely do you find cut marks that intersect each other. They are usually parallel. In accidental knick marks there is usually just the single mark and it tends to be located in a spot that you wouldn’t generally find cut marks (i.e. on joint surfaces or midshaft of a long bone).”

Contrary to initial review in the 1960s, Eliann discovered a few tantalizing signs that this mammoth may have, indeed, suffered from trauma induced by ancient humans.  From a suspicious-looking lesion to a possible puncture wound on vertebrae to a puzzling set of lines in a bone fragment, there was reason to wonder whether humans had been responsible for these scars.

Ultimately, however, the first two were determined to be pathological. The lesions conform to known understanding of malnutrition in the form of osteolytic lesions.

Knowing her hope to find evidence of human interaction, I asked if this was a bit of a disappointment.

“[I]t was a bit of a kick in the knees,” she admitted, “but still a super interesting avenue of study in terms of pathology. I am more than thrilled with my findings though!”

Another startling discovery appeared in what she describes as a “spongy” bone fragment, shown above, which contain traces of blood vessels.

“I remember bringing it to my supervisor and we both scratched our heads over it…So we called on our resident bioarchaeologist Dr. [Angela] Lieverse to take a look and she wasn’t sure but suggested possibly something vascular. Sure enough, when I searched for studies fitting that criteria, a couple articles turned up. So it seems that it is an occurring phenomena but possibly not that common,” Eliann wrote.

Ultimately, Eliann determined that this was a young male woolly mammoth (between 28 – 35 years old) that was still growing at the time of its death.  She estimates it was 328.66 cm (approximately 10.8 feet) tall.  While the large open wound on one of the vertebra points to a possible puncture wound from Clovis weaponry, other pathological features point to a mammoth suffering from malnutrition.

Eliann’s enthusiasm for those who helped her in her research was apparent.

“[T]he folks at the [Royal Saskatchewan M]useum were more than happy to help in any way possible,” she expressed, “and it is something that I have always appreciated! Also my major funders [were] the Saskatchewan Heritage Foundation, the Saskatchewan Archaeological Society, and, of course, the Department of Archaeology and Anthropology at the [University of Saskatchewan].”

More than just a strenuous academic endeavor, Eliann’s research has painted a picture that has been missing for decades on a significant local paleontological find.

“The [people in the] town of Kyle identify with this mammoth.  As you come into Kyle, there’s this statue of a mammoth.  Their sign that says ‘Welcome to Kyle’ has a picture of a mammoth on it.  It’s clear that they identify with it.”

 

 

A Mammuthus primigenius-sized THANK YOU to Eliann Stoffel—not only for her time in emails and by phone–but also for her gracious permission to use a number of pictures from her work!  Her thesis is fascinating and well written.  I recommend it to all!  Eliann, may you find many mammoths with evidence of human association in the future!

Another enormous thank you to Dr. Angela Lieverse, head of the Department of Archaeology and Anthropology at the University of Saskatchewan, who was also responsible for the generous use of images from Eliann’s thesis!

And I am very grateful to Dr. Emily Bamforth at the Royal Saskatchewan Museum for connecting me to Eliann! I could not have written this otherwise. THANK YOU!!

Meet Dr. Katy Smith – Mastodon Detective

If you imagine the Great Lakes region over 10,000 years ago, you might see large, hairy beasts with relatively straight tusks grazing around boggy areas or moving within dense forests.  Their fur and overall appearance might cause you to confuse them with woolly mammoths, but these are the mammoths’ shorter, stockier cousins.  And if any of them would let you get close enough to inspect their mouths, you’d see in an instant that their teeth are completely different than those of mammoths.

Whereas mammoths are believed to have eaten grasses and even flowers, mastodons needed teeth suited to the mastication of hardier stuff: shrubs, parts of trees, perhaps pinecones?   Mastodon teeth, with the bumps and ridges one might associate with carnivores, are easily recognizable as ‘teeth.’  Mammoths, in contrast, needed to grind food, producing teeth with spherical lengths of ridges across each tooth.

And while woolly mammoths pervade popular culture and interest, there are some, like Dr. Katy Smith, Associate Professor of Geology at Georgia Southern University and Curator of the Georgia Southern Museum, who prefer their lesser-known cousins and have made fascinating contributions to our understanding of them.

Mastodon discoveries usually produce the fossils of a single animal, and rarely a complete skeleton. Rarer still, finding skeletal remains of multiple mastodons at the same site.

Such a unique discovery occurred in 2005, when more than 300 fossils were found in Hebron, Indiana.  Now known as the “Bothwell site,” it was originally going to be the location of the landowner’s pond.  Instead, Indiana State Museum paleobiologist Ron Richards and his crew uncovered bones that included numerous mastodons (Mammut americanum), giant beaver (Castoroides) and hoofed animals with even-toes (artiodactyls).

 

[images of the Bothwell site dig, courtesy of Ron Richards, Indiana State Museum, for this post: Mammoths and Mastodons in Indiana – Part 2.]

 

Four years later, the Bothwell site became the focus of Katy Smith, her dissertation, and two subsequent papers she co-wrote with Dr. Daniel Fisher at the University of Michigan.

But let’s take a moment to consider what paleontologists uncover. However rudimentary this may seem, it is important to note that bones are generally not discovered in neat order, intact and with each skeletal component attached where it would have been in the life of the animal.

Consider, too, that not all bones survive.  And those that do are often broken or in terrible condition.

So even at a site such as Bothwell, which produced lots of fossils, a paleontologist’s job is no less challenging.  The pieces of information are incomplete, mere clues to the animals that died there.

The questions, however, are profuse.

Why were so many animals found in that one spot?

If, as it is currently debated, mastodons shared behavioral traits with modern-day elephants, was this a family unit?

If so, was this group—like elephants–comprised largely of female and juvenile mastodons?

And why were other unrelated animals discovered among them?

Did a sudden disaster kill them all?  Were humans involved?

Sexual dimorphism is another way of referring to the traits that make an animal either female or male.  Some of us would assume, since mastodon pelvic bones were not among the Bothwell fossil assemblage, that the sex of these animals would remain unknown.

There were 13 mastodon tusks, only four of which were complete. And this, remarkably, is what prompted Katy Smith’s research.

“I wanted to know if I just had tusks, what can I do to figure out if I’m looking at a male or a female,” she explained by phone.

 

[image of Dr. Katy Smith measuring an African elephant tusk in (what this author believes must be one of the greatest places on earth) the basement and fossil collection of the University of Michigan; courtesy of Dr. Katy Smith]

 

“Other people have looked at [sexual dimorphism], but I wanted to look at it specifically with the Bothwell mastodons, because they were inferred to be female, and female mastodons are less common in the fossil record than males.

“When I presented preliminary results from my research in a paleontology class, the professor said, ‘Why don’t you try multivariate analysis?’ And it just kind of spiraled from there.”

‘Multivariate analysis,’ as the name implies, means using more than one type of measurement or observation towards a hypothesis.  In other words, rather than simply using size as a determination of sexual dimorphism, applying numerous methods and statistics that support or disprove it.

Already, the amount of information scientists have pulled from tusks alone is fascinating.

Tusks are teeth.  They are described, in Dr. Smith’s dissertation as “hypertrophic incisors.” And, unlike human teeth, they continue to grow the entire life of the animal. So where we can simply look at a human tooth and know immediately whether it is from an adult or a child, the same cannot be done with tusks.

What their hardy structure records includes the age of the animal, growth in winter or summer months each year, their overall diet, and periods of nutritional stress.  (As described in an earlier post, Proboscidean molars can even provide details regarding where they roamed during life.)

But much of this information can only be gleaned from well-preserved, intact tusks, as well as from cutting into and examining their chemical composition.

“If you don’t know what the sex of the animal is before you look at tusk microstructure,” she said, “it can be hard to interpret what you’re looking at.”

Part of what Dr. Smith hoped to discover were similarities in the tusks where sex and age had already been determined.  If certain structural elements were the same across female mastodon tusks, such that they tended to differ from male mastodon tusks, this might help determine sexual dimorphism in future tusk discoveries.

She also hoped to discover any similarities between the tusks of extant elephants and mastodons.

Thus, she studied and measured tusks of both species from numerous museum collections. (Asian elephant tusks were not used, as female elephants of this species tend to have either tiny tusks or no tusks at all.)  She rather amusingly refers to the approximate amount of tusks involved as “5,000 pounds of tusk.”

Her dissertation and the two papers describe the type of analysis performed in detail.  Among them were canonical variates analysis (CVA) and discriminant function analysis (DFA).

“Fortunately, we didn’t have to cut into the tusks to do those measurements. You just insert a stiff wire into the pulp cavity.”

“We think about tusks sometimes as stacks of sugar cones, because they actually grow in a kind of [layered] cone structure. So you think about one sugar cone, and then you put another one inside that one and then another one inside that one and so on and so forth. And the last sugar cone is empty. There’s nothing in it. That represents the pulp cavity.”

“[Analyzing the] pulp cavity is probably one of the best single measurements that you can use to distinguish between male and females. [I]n females, that pulp cavity will terminate before the gum line, and in males, it will terminate after the gum line, closer to the tip.

“This is something that we saw in almost every mastodon. So it was kind of cool.”

“If we could have cut every tusk, I would have,” she admitted, and laughed. “But it was a matter of collecting these measurements at different museums. And so I would just go there and collect all of them, and that was how we’d get the pulp cavity depth.”

“I’ve always been interested in paleontology,” she said when I asked her how she got started.

“I’m one of those kids who just never grew out of it. My parents used to take me to the museum all the time, and I used to spend hours and hours staring at the dinosaur dioramas there, just loving it.  I told my kindergarten teacher I wanted to be a paleontologist. I never changed! My 5-year-old self grew up and became a paleontologist.”

But her interests moved away from dinosaurs when she realized that their fossil record in Wisconsin, her home state, was rare to nonexistent.

After all, she said, “I started just wanting to explore what was underneath my feet.”

It wasn’t until grad school at Michigan State, where she met the late Dr. Alan Holman, that she realized her passion for mastodons.  His own interest in the species was infectious, and it was through him that she learned of the numerous mastodon (Mammut americanum) fossil discoveries in the area.

“Wow!” she said, recalling her initial reaction. “There are over 300 mastodons in Michigan. This is exciting!”

[image of male mastodon skull and tusks, courtesy of Dr. Katy Smith]

Not surprisingly, she did her PhD work at the University of Michigan, home to Proboscidean expert Dr. Daniel Fisher, who was her advisor.

“I wanted to work with him,” she explained, “because I wanted to continue working on mastodons, and he had a couple of ideas for projects. One of them included this assemblage of mastodons from Indiana, which were—supposedly—all female.”

What she discovered regarding the Bothwell site is both thought-provoking and fascinating:

• 8 tusks were determined to be female; the other 5 are unknown
• the ages of the mastodons range between 19 and 31 years old
• there is evidence that at least one juvenile might have been among them (a “juvenile tooth crown” was found)
• given that two mastodons died in winter, and another two died either in late summer or early autumn, this indicates that the collective deaths of these animals didn’t happen at the same time (hence, not a single event)
• none of the mastodons appeared to be under nutritional stress when they died
• members of a family unit would be expected to have the same “isotope profiles”–chemical signatures in their teeth–but these do not

Based on the evidence provided, Dr. Smith wonders whether these animals were part of a meat cache for humans (members of the Clovis culture) that co-existed at that time.

But perhaps the single most remarkable result of her research is helping other paleontologists–who often have nothing more than a single tusk–determine the sex of that animal using her different types of analysis.

Prior to her dissertation, only one female mastodon tusk had been analyzed for growth rate.  To date, I am unaware of any other publication (paper or book) that helps detail the sexual dimorphism in mastodons by tusks alone.

When I remarked upon this, I asked her if others had cited her work.  Her response, after stating that others had, was equally fascinating to me.

“It’s always the hope as a scientist that you’re contributing in some way,” she said, “and you know that you’re contributing if somebody else is using what you’ve done.”

 

An enormous and sincere THANK YOU to Dr. Katy Smith for her generous and fascinating answers to my many questions, her gracious help when I had trouble understanding certain points, and for being so much fun with whom to connect! I cannot express how much I wish I could attend her classes, nor how fascinating I found her dissertation. I am profoundly grateful that she shared it with me!

A sincere thank you to my Dad, as well, for helping me understand tooth components (i.e.: dentin, cementum)!

These Two Museums Need Your Help: Pt. 2 Illinois State Museum

Actually, the title to this post is a misnomer: there is one main branch of the Illinois State Museum in Springfield, but there are 4 other state museums in different locations that also fall under the “Illinois State Museum.”

And all five of them are under the threat of closure on July 1^st.

On June 2^nd, the office of Governor Bruce Rauner announced what programs he intended to cut in an attempt to save $400 million in the Illinois state budget.

As these museums fall under the responsibility of the Illinois Department of Natural Resources, the Governor’s press release stated that the [IDNR] “will begin the process to suspend operations and close the five state museums to visitors. The state will continue to maintain and secure the museums to protect the artifacts and exhibits.”

You can read about the many other program cuts and their potential impact here in this article in the Chicago Tribune. (http://www.chicagotribune.com/news/local/politics/ct-rauner-madigan-budget-cuts-met-0603-20150602-story.html)

 

The idea of shutting down one museum—let alone five—seems incomprehensible. These museums collectively contain millions of artifacts.

Chris Young, a spokesperson for the IDNR, wrote in an email that the number of visitors to all museums last year was 386,750 people.  The specific number of people for each museum in 2014 is as follows:

• Illinois State Museum main facility in Springfield plus Research and Collections Center:  199,304
• Dickson Mounds:  50,297
• Chicago Gallery:  64,300
• Illinois Artisans Shop Chicago:  39,896
• Lockport Gallery:  14,253
• Southern Illinois Art Gallery:  18,700

These numbers do not take into account the online resources provided by the museums nor the collaboration between researchers in other states or countries.

Enter Samantha Reif.  According to an article on NPR Illinois, she is both a museum volunteer and a geology teacher, and she created the MoveOn.org petition asking Gov. Rauner not to shut down the museums.  At the time of this post, there are 4,514 signatures.

But if the threat of shuttering them becomes real, how does one actually go about closing museums?

“The museum will return art objects owned by other entities that are currently on display,” Chris Young of the IDNR responded. “Consigned Illinois Artisan works also will be returned, as well as scientific collections from other museums and universities that have been borrowed for research purposes.”

“The museum’s staff will also be calling back artifacts and specimens that are on loan to other entities for research and exhibition,” he continued. “At this time, there is no definitive list of objects or collections to be returned.”

In addition, he wrote that the “museum currently has three active research grants from the National Science Foundation, and is a partner on a NSF education grant. [The] museum administration is working on a strategy for completion of the current grants.”

He noted that there are 68 people employed throughout these museums, but that lay-off notices have not yet been sent.

“Closure will come after the museum’s professional staff has adequate time to ensure that collections are properly accounted for and stored. No specific date has been set for closure as details are still being worked out.”

NH State Fossil? – Part 4: Legislators to Students: “NO.”

“I don’t mean this in any unkind way, but not all bills pass, and that’s part of the lesson associated here.”

Representative John Sytek was discussing the bill to make a mastodon the NH State Fossil (H.B. 113).

“I’ve had my own bills not pass,” he continued. “And, well, that’s life!”

He and 19 other members of the NH House of Representatives were part of the committee responsible for hearing testimony in support of the bill. These representatives would then offer their recommendation to the rest of the 400 members. The full House would then vote on whether to pass the bill.

[image of the NH State House, Concord, NH, taken by the author]

 

In other words, at a time when the House was voting on hundreds of other bills, the recommendation of that specific committee was crucial to this particular bill.

Of the 20 committee members, only four were present for the testimony.

A small group of 4th graders, Thom Smith and two local paleontologists—Dr. Will Clyde, UNH, and Dr. Gary Johnson, Dartmouth—presented their arguments in support of a state fossil late that afternoon on February 3rd.

The recommendation of the committee, voted 11-4 against the bill, was “inexpedient to legislate.”

“Remember, we were listening to a bill having to do with a symbol for the state. An icon,” Rep. Sytek explained by phone.

“This wasn’t a bill about the budget. This wasn’t eminent domain. This wasn’t licensing of doctors.

“All I’m saying is this bill, in and of itself, was interesting, and we’ve respected the efforts that the kids made, but this isn’t amending the constitution.

“So people who had other obligations want to meet their other obligations. And like every legislator, or everyone in life, you’ve got to balance one thing against another.”

[image of NH State House front stairs and entrance, taken by the author]

 

Representative Greg Smith, one of the committee members not present for the testimony, answered questions later by phone about the bill and the legislative process.

“Basically,” he said, “we’ve got [hundreds of] bills. In a short couple of months, meeting one or two days a week, we’ve got to get through all those bills. And we’re basically volunteers.”

“I think timing-wise, the timing didn’t work out. I think this was intended to be one of the first bills that we saw, and, if you recall, we had such a snowy winter that a lot of the testimony [was] delayed.

“I wonder if things had been different, if this had been one of the very first bills we heard, the House might be more receptive to passing a bill early on like this.

“If we’re only sitting around for 2 hours and then we’re going home, it’s a lot different. Now,” he said, in reference to the number of bills in the House, “you’re in the traffic jam.”

Inclement weather this winter (a season, I might add, that even now, in April, is not yet over) prevented hearings from occurring as scheduled. Hearings were rescheduled to be heard on one long, full day versus over several days or weeks. Time was indeed a factor.

 

[Here is where bills are either passed or not passed. Image inside the NH State House, taken by the author]

 

And it’s easy, I think, to scoff at something such as a proposal for a state symbol or dismiss it as inconsequential in relation to issues like the budget.

But isn’t there substantial value in an engaged group of citizens, especially at such a young age? Isn’t this something we want to encourage, in a country where most adults are cynical of and many are ignorant of the political process?

And isn’t there great value to furthering educational and scientific resources, at a time when the country is concerned about both?

This is not to say that I think legislation should be passed simply because a group of young citizens are engaged. And I am also not suggesting that all educational or scientific bills be passed on the premise that they are related to education or science. But it did make me wonder why—beyond time and the subjective determination of importance—so many voted against it.

This is particularly puzzling when Rep. Sytek made a point to explain that the testimony given by the 4th graders was superlative.

“I want to commend [Thom Smith] for the work that he did in instructing and teaching these young citizens how our process works.

“Whether anything came of it or not, it’s virtually a dress rehearsal for their own time in the legislature. Because I think some of them will be there! The kids were remarkable! The passage or non-passage of the bill had nothing to do with the presentation.

“I made a point of telling the rest of the committee that this was one of the best presentations I’d seen,” he explained. “Now, I’m not talking about the Department of Health and Human Services necessarily; I’m talking about when interesting constituencies come: high school kids, maybe grammar school kids, a local organization trying to push something for their town comes in.

“This was really dynamite. I appreciated the effort [they made.]”

[image inside the NH State House, taken by the author]

 

So what were the reasons?

Would creating a state fossil require funding from the state? Would it involve more work for the legislature? Was the research, reasoning or quality of the testimony lacking? Did the legislators think a different fossil would make a better symbol?

What, outside of personal feelings regarding the symbol, would prompt a representative to vote against it?

Rep. Greg Smith was frank.

“I think it’s a bit subjective. You might get different answers from different people.”

“[T]here seems to be an effort by some fourth grade classes, as part of Civics [class], to try and submit bills for different things. [This] fossil bill is a good example.

“I think these are very worthy lessons. It’s great that the fourth graders are involved. But folks also need to understand that when we vote ‘yes’ on something like this, we’re telling the rest of the House, ‘hey, you guys should take the time and go vote on it and send it to the Senate’ because it’s that valuable.

“I think that’s where a lot of us have a concern: that the time we spend on things like the state raptor or the state fossil takes time away from other subjects that we don’t have as much time to research and debate. [This is] my opinion, but I think I speak for a number of others.

“I didn’t have any objection, you know, mastodon vs. mammoth,” he said in response to whether he disagreed with the choice of fossil proposed. “It was really more around that I didn’t feel that the state needs a state fossil.”

“We had a bill come to committee on a state poem,” he continued. “I was out of town that day, but I would have voted against it. I actually lead the charge against an effort to make Feb. 6 Ronald Reagan Day in NH, because Ronald Reagan never lived here, never grew up here. I’m a Republican, and I still thought that it wasn’t appropriate.

Rep. Sytek offered similar reasoning.

“It is true that it could easily be passed in the sense that it didn’t cost the state any money,” he said. “The question, I think, for some people is the appropriateness of talking about something like this when we’re faced with an enormous budget shortfall.

“It looks inappropriate to be talking about things that are of no fundamental significance to the Republic at a time when [we’re working on] the whole tax structure, spending on worthwhile social projects [such as] mental health issues [or] the condition of our roads and bridges. We can talk about everything. We’ll stay there as long as it takes to get the job done. But it doesn’t seem right to be talking about this.”

Rep. Greg Smith highlighted the scarcity of fossils in the state as a reason not to have a state fossil.

“[I]f we’re going to do something to make the State of NH Whatever,” he said, “there needs to be a strong and unique connection to NH.

“[L]et’s say, we found the biggest Tyrannosaurus rex fossil in the world and we found it in NH, well, that would be kind of interesting and unique.

“If we found more mammoths or mastodons in NH, [if] we found 100 mastodons, and it was world-famous, well, that would be kind of compelling. Something that makes it a connection to NH, not just a fossil for the sake of having a fossil.”

New Hampshire’s geology, however, makes it exceedingly difficult to find the type of fossils he described. As mentioned in the previous post, the geological components within the state do not preserve fossils as well as that of other states. Does that mean that the state should not celebrate the remarkable fossils it has?

“I feel bad, in a way, for the kids because I know they put a lot of time into it, but I would also say that they’re operating in an adult environment,” Rep. Smith stated. “And I saw a lot of really good bills that representatives put a lot of time into that would have, I believe, positively affected the citizens of NH, but they were voted down or they were killed off by special interests. So, I don’t want [the] fourth graders to be discouraged, but again, they’re being treated as adults. We’re not coddling them just because they’re fourth graders.”

“That may sound mean-spirited. It’s not meant to be, but it’s part of reality.”

The bill, not surprisingly, did not pass the NH House. And it cannot be introduced again for another two years.

“[T]hings don’t necessarily pass the first time around,” Rep. Smith said. “If it’s voted down, you can’t introduce the same bill in the same session. [I]n two years, you’re going to have 20-25% of the House turnover. So maybe they come back in two years and try again.”

“And,” he advised, “if you can get a more senior person or maybe a State Senator to weigh in, that carries weight. And then it becomes more of a personal favor. But you know, the committees, we pay attention to that sort of thing, too.”

Below are emails sent by some members of the committee to Thom Smith, published with permission by those who sent them.

Dear Mr. Smith,

Thank you for writing. In short, I voted against this bill because I believe we have too many state “this or that”, too many special days, and too many special people days that we recognize already. Our committee also killed a day in recognition of Ronald Reagan recently as well as the adoption of a state poem, and last year the House tabled a bill creating state colors. It is also possible the House may table the pending Bobcat bill.

Though I realize your students must be very disappointed in the disposition of this bill, this is a great learning opportunity for them. I have sponsored many bills, most of which, by a huge majority, have failed to become law. No small effort was exerted in an attempt to see these bills pass and yes, I was disappointed.

The House has had well over 800 bills filed this session, can you imagine if even 50% of them had become law? Your students have learned a great lesson from the legislative process they experienced and failure is one of those experiences.

Thank you again for writing,
Steve

Mr. Smith,

Unfortunately, I was busy at another hearing during the public session and at a work obligation for the executive session, so my comments are only of limited value.

With that said, I would have likely voted against passage as this committee has a significant amount of work and bills like the state poem and this one take us away from oversight of the various boards and the pension system. In general the committee is one of the busier ones and these extra bills do not get the attention they may deserve. One must consider that we are volunteers and in the case of myself, someone who works a full time job outside of Concord, cannot afford to take more than two days off each week to address this legislation.

I would love for a school class to take on a more technical issue, for example do we really need laws about cutting of hair, or what age to go to a tanning salon, or what requirements need to be met to paint someone’s nails……

Having sponsored/co-sponsored the 3rd most bills this year in the house, one gets used to bills not making it through the system. The founders intentionally made it hard to get a bill passed just to minimize how quickly changes to our government can take place. Specifically there are 3 separate gates [ House, Senate and Governor] to get through before a bill becomes law and this adds a significant amount of impedance to the system and this tends to slow down how quickly a statutory change is made.

FWIW, there are bills that I am working this year that are now in their 12th year and we may actually pass both chambers for the first time.

Please share the following quote with the students:
Never, never, never give up.

FWIW, I would love to see a public classroom take a stand on drivers ed bill, or finding a solution to the “smarter” “balanced” assessments debacle.. There are some real issues that need to be addressed in the state and it seems our committee is not working on any of the critical issues.

Best regards,
Rep. Hoell

Mr. Smith:

Here is the committee report that will appear in the calendar for this bill:

HB-113. This bill would designate the mastodon as the official state fossil (as does Michigan). It is the result of the third (now fourth) grade class project at Bradford elementary school. The Committee was impressed with the quality of the effort. The pupils enlisted the aid of both UNH and Dartmouth professors. Three well-spoken pupils stated their case in testimony before the Committee. However, the Committee felt that New Hampshire has enough cultural and historical artifacts such as our state motto, flower and bird. There was no compelling evidence to indicate that the lack of a state fossil would detract from the imagery of our state nor would adding this designation significantly complement the extant array of our state emblems.

My own personal comments follow.

The members who heard the presentation by your class were genuinely impressed by the obvious work that you as a teacher (I teach at Salem High, BTW) and your pupils did. It is often true that many members (of a citizen legislature) cannot be present for every hearing. However, they are used to reading bills, listening to other members of the Committee and making reasonable judgments on those bases.

However, to varying degrees, the majority of the committee simply did not feel that we need an official state fossil, regardless of the quality of the presentation. One of the professors said that this would raise public awareness of paleontology. I simply do not see that that is true nor do I see that as persuasive even if so.

Many bills are introduced and most of them do not get passed. That is a reality that every legislator understands. Last term, we had a similar presentation by schoolchildren who wanted to see NH adopt orange and red as our official state colors. That bill did not get passed for similar reasons.

Your class should understand that we turn down even requests from the Governor. The legislative process works slowly and persistence (i.e. future efforts) often are successful.

I hope this helps,

——————————————————

I cannot extend a large enough THANK YOU to Thom Smith or his marvelous students.  I am so very impressed and grateful for their efforts, and I am so very sorry that the bill did not pass.

Thank you again to Representatives David Borden, Nancy Stiles, and Tom Sherman.

And thank you so much to Gary Andy.

Thank you to Representatives John Sytek and Greg Smith for their time and their responses to my questions. Thank you to Representatives John Sytek, JR Hoell and Steve Beaudoin for being willing to share their emails and the reasons behind their vote.

While this segment from Last Week Tonight with John Oliver is not about the state fossil bill, it is about the bill to make the red-tailed hawk the state raptor.  This bill was introduced at the same time, and it, too, was voted down.

NH State Fossil? – Part 3: Proposing a Mastodon

I’d forgotten what it is like to be in an elementary school. Stepping into Kearsarge Regional in Bradford, NH, brought it all back: hallways with drawings hung on the wall, classrooms bustling with activity, and a crowded front office where the friendly receptionist—to my delight!—called Thom Smith on an enormous and antiquated buzzer system.

Thom is one of the two third grade teachers, and he’s been there for seven years.  We were meeting that winter day to discuss efforts toward creating a state fossil. He and his now former students had been working on this since October 2013.  It was now 2015; his third graders were currently in the 4^th grade.  This had not, apparently, been an easy process.

[snow in downtown Concord, NH this past winter, picture taken by the author]

 

Ask any elementary child about that state’s symbols, and that child will probably be able to tell you—most likely, with pride–what they are.  Ask an adult, however, and I’d be surprised if they knew more than a few of them.

State symbols, such as an official state bird, an official state fossil, etc., vary from state to state. Generally, they represent a specific flora, fauna or other item found abundantly in that state, so they vary depending upon the environment of the area.  There are no set rules to this, no requirements, no quotas. But a state symbol must be voted upon before it becomes official, so it does require an interested and active group of citizens to propose and see it through.

 

 

[image of the NH State House, picture taken by the author]

 

Thom and these students, with help from Lauren Simpson—one of two 4^th grade teachers—were trying to make a mastodon (specifically, Mammut americanum) the NH State Fossil.  That type of mastodon was abundant throughout North America, and it is one of the rare fossils found to-date in NH.

I was thrilled to learn of their project and wanted to hear more.

But this project was not without challenges from the start. New Hampshire, unlike many other states in the country, is fossil-poor.

This is not to say that extinct species of any previous time period didn’t exist here.  It simply means that the geological components within the state do not preserve fossils.  Fossils are that much harder to find, which makes the rare mammoth and mastodon tooth discoveries incredibly exciting.

Unfortunately, most people don’t realize this. And when dealing with something such as a state symbol—which generally indicates an abundance of that specific item—the immediate reaction is to assume that NH doesn’t merit a state fossil.

That January, Thom was optimistic.

 

[Thom Smith, his marvelous students, and Rep. David Borden, image courtesy of Thom Smith]

 

I was struck by his genuine warmth and graciousness.  He was eager to talk about the project and his students.  He had, he mentioned when I worried about the time, specifically crafted his curriculum for the day so that we could speak uninterrupted for the next 40 minutes.  We sat amid a sea of tiny chairs and desks.  Our conversation may have been adult, but I was acutely aware of how young the students are, marveling as I learned about their enthusiasm for both science and the political process.  These were passionate kids with an equally passionate teacher.

“When you can apply what the kids are learning to current events and what’s going on around them,” Thom explained, “it makes it a lot more meaningful.”

It was his students themselves that prompted the project. They had learned about fossils soon after learning about civics, and they were concerned that, of all New England states, NH alone does not have a state fossil.  They were the reason letters were written to local representatives in the beginning, and it was the students’ consistent interest and follow-up to Thom that prompted him to reach out to representatives in Rye, the town near which mammoth and mastodon fossils were discovered.  (These fossils were found by Captain Mike Anderson and his daughter, Kelsi, fishing off of the NH coast.)

 

 

When two of those representatives expressed an interest, the project started moving.  Congressmen David Borden and Tom Sherman jumped on board, eventually leading to other support within the House of Representatives, including Congresswoman Nancy Stiles, who was the third co-sponsor of the bill.

Representative Borden, however, seems to have taken a particular interest in the students, their teacher and the entire process.  He and his wife met them when the class visited Odiorne Point State Park.  He has visited them in Bradford as well, introducing the students to his dog.

With no little enthusiasm, Thom said of Rep. Borden, “He’s been amazing.”

The class also had the help of Dr. Will Clyde from UNH and Dr. Gary Johnson of Dartmouth, two paleontologists with whom they conferred to determine the best choice for a potential state fossil.  Both men also agreed to testify in support of the bill.

It seemed to me that this bill was in very good hands.  Thom and his students were organized, they had done their research, and they had the help of people in the field to support them.  While Thom expressed a little nervousness about the outcome of the vote, I was confident it would pass.  And why shouldn’t it? It seemed an easy vote: solid research, a unique state symbol, an engaged group of young citizens who were also interested in science, and—at a time when the budget is forefront in everyone’s minds–a bill that didn’t require any financial backing from the state.

How horribly naïve of me to think so.

Next up, last post in this series: the legislators vote and explain their vote.

NH State Fossil? – Part 1: Interview with Thom Smith

In the Fall of 2013, Thom Smith and his 3rd grade class in Bradford, NH began their quest to create a State Fossil.  After much research and consultation with local paleontologists, Mammut americanum (a type of mastodon that most likely resided in NH) became their fossil of choice.  They were finally able to present their testimony to a committee within the NH House of Representatives this past February.

The story does not end well.

And it is a story that did not get as much attention as another proposal for a State Raptor proposed by 4th graders from a different NH town.

Rather than begin the story with my version of events, I wanted to let Thom Smith and these marvelous students speak for themselves.

Below is the initial Q&A exchanged between Thom Smith and me this past January.

[image of Thom Smith with his students and Rep. David Borden, the first NH legislator to take an interest in the bill, courtesy of Thom Smith]

1. How do you discuss fossils with your students?

Thom Smith: Instruction of fossils is centered on the idea that discovering fossils is equivalent to discovering clues about our past and our planet’s past.  Fossils are clues that help us look into the lives of ancient animals and plants.  Students become excited when they discover that paleontology is not just digging up old things, but about being a detective looking for clues that will help tell us the history of our backyard’s past.  We delve further into fossils by learning about the four main types of fossils, as well as by participating in a “mock” paleontology dig on our school’s fitness and nature trail. 

2. How did you (or do you) learn about fossils/paleontology?

Thom Smith: I initially learned about paleontology in elementary school as well.  To be honest I do not remember any further education in paleontology beyond that point – except perhaps teachers occasionally touching upon paleontology matters in other science classes.  I currently learn about fossils by reading up on any current event article that comes to light in the news, or by reading about recent discoveries in magazines or online. 

3. What was it about this class that inspired you to try to have a state fossil created in NH?

Thom Smith: It was a shared inspiration, and honestly, it was my students that originally came up with the idea.  When studying fossils my students often discover through readings and research of their own that New Hampshire does not have a state fossil.  This past year was no different, and when they became discouraged at that fact I asked them if they wanted to try and do something about it.  We had just been involved on a unit of study on citizenship, and I thought it might be a good opportunity for them to see what speaking up for their concerns as citizens might do.  As a third grade teacher, I also get the privilege of instructing our students on the New Hampshire state “officials”.  Every year students become greatly interested in learning about the ladybug, the Karner Blue butterfly and the purple finch.  I also encouraged my students to try to have a state fossil declared in New Hampshire because I knew it would help increase student interest in paleontology and the importance of learning about our state’s ancient past if a bill was to become law. 

4.  Have you had any experience with legislation before? (How have you found the process so far?)

Thom Smith: I have not had any experience with legislation before, yet the process so far has been very educational and encouraging.  Representative David Borden, who was the first state representative to offer our class his assistance, has been incredible.  He is a kind, sincere individual who really cares about our state’s youth and education.  He has gone to great lengths to encourage and educate our school’s students about state legislation, and has done so with a humble and generous attitude.  He understands that this quest for a state fossil is not just because some students in a small town in New Hampshire want one, but because these students who wish to have a voice have good reasons for their request and need supportive adults to help them.  The process of legislation takes a lot of time, but I think it is understandably so, at least in this circumstance.

 

5. The Concord Monitor article indicates that you connected with Dr. Gary Johnson at Dartmouth and Dr. Will Clyde at UNH. What prompted you to connect with these two people? What have you learned from them?

Thom Smith: The class initially needed advice on discerning which fossil they believed would be the best fossil to represent our state.  I connected with Dr. Will Clyde at UNH because the class watched a news clip on WMUR that featured Dr. Clyde providing his expertise.  I connected with Dr. Johnson because I searched online for other experts on fossils from New Hampshire and discovered that his sedimentary geology field of study led him to the discovery of fossilized dinosaur footprints.  Both professors were immediately helpful and encouraging.  We learned that New Hampshire is not a good state in searching for fossils because of its granite make-up, but that fossils have been found in NH, including brachiopods, mammoth and mastodon fossils.  The mammoth and mastodon fossils had been found more recently, including by fishermen off the coast of Rye.  We more recently learned of support for our classes’ request from Professor of Geology Wallace Bothner at UNH as well.

6. Did your students think anything other than a mastodon should be the state fossil?

Thom Smith:  I found the decision to determine what fossil should be our state fossil another good lesson in citizenship responsibilities. Our class made a chart with brachiopods, mammoths and mastodons, and in each column we wrote down facts about each fossil and how it related to our state.  We discussed the possible “candidates” for a couple of class sessions then held a big vote.  The mastodon won unanimously for a variety of reasons – ones we outlined in a letter that we sent to state representatives asking for support.  Those reasons included:

• This fossil was found recently off the coast of New Hampshire
• This fossil is an official state fossil in only one other state
• Two well-respected paleontologists from New Hampshire suggested it as a possible official state fossil
• This fossil connects our state’s present (New Hampshire’s fishing industry) to our state’s past
• This fossil is a piece of our state’s ancient history that we should recognize, and as an official state fossil has the potential to encourage others to learn about our state’s ancient past
• Our surrounding states have state fossils but New Hampshire does not

 7. Do they understand what a mastodon is?

Thom Smith: My students understand that the mastodon is an extinct, shaggy-haired elephant-type creature, similar to the mammoth except often smaller, and with shorter legs and flatter heads.

[image of Cohoes mastodon at the NY State Museum in Albany, picture by the author]

[painting of mastodons from an exhibit at the Indiana State Museum, courtesy of the Indiana State Museum for this post]

8.  Have they seen the mammoth tooth at the Rye Public Library?

Thom Smith: We have yet to see the mastodon tooth (as well as the mammoth tooth) that were found off the coast of Rye, but hope to soon!  Dr. Will Clyde has seen the mastodon tooth and it is one in excellent shape.   The interesting connection to Rye is that our class also learns about the rocky shore each year and visits Odiorne Point, near the location of where the mastodon fossil was found.  Last June Representative Borden and his wife met us there on our class field trip – it was a great experience.

9. What can people do to help (if anything) with the establishment of a state fossil?

Thom Smith:  Advocate for it.  Publicize the possibility – make it known that this legislation is occurring now and that the more support we have the less likely our students’ bill will be dismissed.  Blog about it (like you are doing), post it on social media, email the possibility of a state fossil to friends and ask them to support the endeavor.  Contacting state legislators is incredibly easy – they are often just an email away, and many are ready and willing to hear your thoughts and voice your opinions in the state house.  The first committee hearing on the possible establishment of a state fossil is January 27^th*, and we hope there are more that lead to this LSR becoming a state law.

[*This date was pushed to February, due to inclement weather in NH at that time–author’s note.]

10.  Are there any questions I haven’t asked that you think would be important for people to know?

 

Thom Smith: I would want everyone to know that this request for an establishment of a state fossil was made by students who had a genuine, valid concern and had the motivation to do something about it.  This request was to change our state’s history so that others might learn more about our state history – its ancient history.  It may be debated as to whether or not the mastodon should be considered our state’s fossil, and a healthy debate would be fine, but we would not want our students’ quest to be lost in arguments that could go round and round when the request for a state fossil is not just about what the fossil should be, but more importantly why there should be one: having a state fossil would result in a lot of positives, including an increased interest in paleontology at a variety of levels, particularly New Hampshire’s youth.

An Ice Age Wonderland – Yukon Paleontology, Part 3

In 2004, scientists in the Yukon discovered a rare and surprising remnant of the Pleistocene: an Ice Age meadow. And some of the grass, although at least 30,000 years old, was STILL GREEN.

[Fossil grass below layer of tephra at Gold Bottom Creek, part of a 30,000-year-old grassy meadow discovered in 2004, from Ice Age Klondike, courtesy of the Government of Yukon. To see a picture of some of the green grass, please see page 33.]

 

In Ice Age Klondike, Dr. Grant Zazula and Dr. Duane Froese explain that this layer—at least 40 meters long–was buried by volcanic ash, or ‘tephra’.

 

[The layer of tephra is the whitish colored portion toward the bottom; 30,000-year-old tephra, image courtesy of the Government of Yukon.]

 

Few places in the world offer us such a concentrated wealth of information about the Pleistocene, and the Yukon is one of them.

“There are a lot of common animals like woolly mammoths and bison and horses that we find all the time,” Dr. Zazula said. “But it’s really exciting when we find the bones or the fossils of the rare species, things like camels, or short-faced bears, or lions. Probably for every 500 bones we find, we might find one bone of a carnivore.”

[Susan Hewitson holding an Ice Age lion humerus, courtesy of the Government of Yukon.]

[Ice Age lion mandible, courtesy of the Government of Yukon.]

“I think that one of the things that has really been exciting for me,” he offered, “is that, in the last 10 years, the field of ancient genetics has really taken off in terms of being able to extract DNA from Ice Age bones, then study the details of evolution and how these animals are related to one another.”

[Geneticist Beth Shapiro examines a partial upper jaw bone of a Yukon horse emerging from the frozen mud at Quartz Creek, from Ice Age Klondike, courtesy of the Government of Yukon.]

 

[Yukon horse jaw uncovered by placer miners on Quartz Creek near Dawson City, from Ice Age Mammals of Yukon, courtesy of the Government of Yukon.]

 

“[The Yukon is] one of the best places in the world to do that because of the bones being found in permafrost. [There are] so many Ice Age bones that are being found, and they’re really accessible.

“So we work really closely with the geneticists all the time; we’re working on all kinds of different projects together. It’s nice to be able to collaborate with a field like that and make fossils from the Yukon available for study.”

[Geneticist Mathias Stiller with tusk found in the muck at Quartz Creek, courtesy of the Government of Yukon.]

This author writes from an area within the United States that is fossil-poor (finding one mastodon tooth is an enormous deal, and most years pass without a single reported fossil). In comparison, the amount of fossil bones found in the Yukon staggers the imagination. But that is not all that the Yukon has to offer.

Even those not generally interested in paleontology get excited when they see or hear about mummified Ice Age animals. There is something so much more dramatic, that much more intriguing, about seeing an extinct animal in the flesh.

Dr. Zazula was frank about being slightly envious of Siberia’s wealth in that domain. Outside of Blue Babe, a steppe bison carcass found in Alaska, the most spectacular mummified animals have been found on the other side of the world.

And yet, one cannot ignore that mummified remains—partial or otherwise—are also an exciting part of Yukon paleontology.

[40,000-year-old mummified black-footed ferret discovered by the McDougall family’s dog, Molly, at their placer gold mine on the Sixtymile River, from Ice Age Klondike, courtesy of the Government of Yukon.]

 

One of the more remarkable finds was a partially mummified horse, discovered by Lee Olynyk and Ron Toews in a gold mine.

Internal organs as well as a significant portion of the hide (with mane and hair!) were recovered. One can see this at the Yukon Beringia Interpretive Centre, the museum in the capital city of Whitehorse.

Also exciting, but from the neighboring Canadian Territory, was a discovery in the village of Tsiigehtchic. Dr. Zazula participated in uncovering this animal.

“[We excavated] a good portion of a carcass and a skeleton of a steppe bison, which turned out to be about 12,000 years old. There was still a bunch of hair and stomach and intestines and some of the limb bones were still articulated with muscle.”

He wrote about this in more depth with Dr. Beth Shapiro (image above) and several other colleagues in 2009. Not only remarkable for its level of preservation, this was also the first reported mammal soft tissue from the Pleistocene in “the glaciated regions of Northern Canada.”

[Large fossil steppe bison skull found Quartz Creek, from Ice Age Klondike, courtesy of the Government of Yukon. Not the same bison fossil mentioned above.]

Then in 2010, Derek Turner and Brent Ward found the “oldest reliably dated” Western camel fossil found in what was once Eastern Beringia. As mentioned in previous posts, Beringia was the area that covered most of Siberia, Alaska and Yukon when the land was connected in the Pleistocene.

Derek Turner, Brent Ward and Dr. Zazula explain, in their paper about this discovery, that North America was once home to possibly six different species of camel. (There appears to be some dispute about whether six distinctly separate species existed.) And, contrary to what one might expect, Camelops—the camel genus—originated in Central Mexico.

[Ice Age camel metatarsal (foot bone), courtesy of the Government of Yukon.]

For someone who has never participated in the excavation of either a mummified animal or fossils from permafrost, it was interesting to learn that there is a distinct smell when working with the muck.

[Placer gold mining monitor, Dominion Creek, courtesy of the Government of Yukon.]

“The only thing that’s kind of similar is the smell of a barnyard. But this is a barnyard from 30,000 years ago, and it’s from mammoths and horses and camels. All this rotten stuff that was [once] animals and plants that died a long, long time ago, frozen in the ground, and it’s now starting to thaw.”

The ever-growing research and discoveries from the Yukon paint a vivid picture of a by-gone era. It is, perhaps, the closest thing to a window into the Ice Age that we have.

When asked if there was anything that had not yet been found that he would be thrilled to find, Dr. Zazula didn’t hesitate: a woolly rhinoceros.

“We know that woolly rhinoceros are, so far, only found in Siberia,” he said, explaining why this would be so significant. “They extended all the way to the Bering Sea essentially, but they seem to never have crossed Beringia into North America. There is no fossil record of Ice Age rhinos here. But if they did [cross Beringia], that would be pretty amazing to find one of their fossils.”

Dinosaur enthusiasts, however, may be disappointed.

“In the Yukon, there’s almost no record of dinosaurs or Mesozoic fossils at all. I’ve been working with colleagues over the past handful of years, trying to find dinosaur deposits. But there’s no record of dinosaurs here except for a few handful of things. So, it’s not really [the place to be] if you’re interested in dinosaur paleontology. And that’s fine for me because then I don’t have to get involved in dinosaur work.”

“The Ice Age,” he continued, “is definitely what I’m interested in.”

[Paleontologist Grant Zazula with Ice Age horse skull, discovered this past summer, courtesy of the Government of Yukon.]

Dr. Zazula began grad school in Alberta studying anthropology. Initially, he wanted to become an archaeologist. His undergrad studies focused on Arctic people and research. A strong theme, he explained, centered on the first humans to cross the land bridge into what is now North America.

“I found myself becoming more interested in the environments that those first peoples in North America were encountering,” he mused. “Instead of just trying to study the people themselves, [I wanted to understand] them in more of a wider geographic or environmental context. So, I switched gears during my grad school days from anthropology into biological sciences.”

After doing paleoecological work in the Old Crow region of the Yukon, Dr. Zazula was invited to join a group of researchers working in the Klondike.

“We started doing fieldwork at these gold mines, and we kept on running into these strange balls of hay frozen in the frozen mud, in the Ice Age sediments. And we didn’t really know what they were at first.”

So he contacted Dick Harington—a well-known paleontologist within Canada for his decades of work with fossils and gold miners in the Yukon. Dr. Harington thought they might be Arctic ground squirrel nests, and in further conversation, explained that they had not yet been a topic of study. In other words, not much was known about them.

“Over the first summer of fieldwork, I think I collected almost a hundred of these ground squirrel nests. And what was really cool about it is that the group that I was working with specialized in glacial stratigraphy [and] using volcanic ash beds to date sediments.

“Because they knew the age of these different volcanic ash layers that are found in the sediment, we could actually place these ground squirrel nests in different points in time in the past. We were able to develop sort of a time series of these Arctic ground squirrel nests.

“[Over] the next four years, I picked apart Arctic ground squirrel nests that [dated] between 20,000 and 80,000 years old or so.”

These nests are also known as “middens.” In his paper on the topic, Dr. Zazula and his colleagues describe these underground Ice Age homes. What these middens revealed, not just about these specific Ice Age animals, but about the Pleistocene environment at the time, is incredible.

Contained within these middens were ‘caches’ of food—seeds and plants from the area. These tiny plants give scientists a much better understanding of the climate and environment thousands of years ago.

“I think we’ve identified over 60 different plant species in them, and I wasn’t expecting that at all.”

In addition—and much to this author’s surprise–they found fossil insects, including beetles.

“Fossil Pleistocene beetle remains are actually quite common in sediments,” he said. “And they’re actually pretty useful for climatic reconstructions, because most beetles have a very narrow temperature or climatic envelope that they can live within.”

In all of Dr. Zazula’s papers, one can see scientists from a variety of fields as co-authors or in the acknowledgements for their help with research. This was reiterated in our phone conversation: he is uniquely positioned as Yukon paleontologist to provide Ice Age material for a wide-range of study to a wide-range of fields.

“Especially with the Pleistocene,” he explained, “there are so many interconnected aspects of research. You need to have a geologist around. And then, in terms of putting the big picture together, you want to have someone that can reconstruct plant fossils. If you’re just doing it alone, you wouldn’t get much of the [big] picture anyway.

“So we’ve really kind of developed this way of doing things as a team.”

“To me, it’s all so interconnected: the geology, the ecology and the mammals and then the archaeology. You might as well work together to try to accomplish goals, and that’s how we’ve done it. It’s been pretty successful.”

“And,” he added, “it’s a lot more fun that way anyway.”

“Prior to the Yukon government establishing the paleontology program, all of the fossils that were being collected went back to Ottawa for the National collection and the National Museum. So most of the material that has ever been collected from the Yukon is actually not here. It’s in Ottawa.

“The Yukon government decided in the mid ‘90’s that they would like to establish its own program in Arctic archaeology and paleontology. Since that time, fossils collected here, stay here. And the position [of Yukon paleontologist] was created to oversee that.”

It’s a position he’s held for the past eight years, and one can hear his genuine enthusiasm for it in his voice.

“It’s a great job,” he stated. “Sometimes I’m shocked that I get paid to do this. It’s pretty exciting.”

Over the years, Dr. Zazula has been featured in some of the most prominent global media. Some of those include NPR, the CBC, the NY Times, and the National Post. This past summer, he was filmed with paleontologist Dick Mol from the Netherlands by a German documentary team. That documentary has been aired in Europe since this past December.

Not everyone, regardless of their profession, is as comfortable with media or journalists.

“I think there are a lot of people that stay in labs and put their heads down and don’t really interact with the media, but I think it’s really important,” he said.

“[I]t’s one thing that’s never taught: how to conduct interviews or how to take your scientific work and present it or make it relevant to the public. And I think that’s a real problem, because if you are a practicing scientist after graduate school, you’re undoubtedly going to do research that attracts interest, and if you don’t have the ability to speak about it or to present it, you lose a lot of traction. In a lot of regards, science is kind of a big competition. It’s like a big science fair. If you don’t produce results and attract attention, you won’t continue to be funded. You can be an excellent scientist and sort of fade away if you don’t have the ability to attract people’s attention.

“I work for [the] government, where we’re publically funded by tax dollars. [F]or some people, [paleontology] might not seem very relevant for society. Still, I think it’s pretty important whenever we have something new to talk about, in terms of new results or new and interesting things, we should make sure it gets out to the public through media.

“Politicians are the people that decide if these programs continue to be funded. And if they see that there’s a lot of media interest and a lot of people learning because of it, then they’ll definitely keep funding these kinds of programs. And I’m grateful that they continue to do so.”

Explaining the reasons for his fascination with the Ice Age, Dr. Zazula said, “Dinosaur paleontology doesn’t really tell us much about the modern environment. If we’re interested in what we have today and how it’s changing because of, say, climate change, or environmental change, we’re not going to get much information about environmental processes by studying dinosaurs.

“The study of the Ice Age, [however], is how the modern world came to be.

“When you think of tens or hundreds of thousands of years ago, it may seem like a long time ago, [but] it’s just a geological instant. And in that short time period–in that geological instant–the changes that have happened to result in what we have here today are amazing!

“To think of giant elephants and lions running around North America: it’s such a different world. And yet so many aspects of that world can inform us of what we’re dealing with today.”
