New profile, so here’s an intro post! I’m a paleontology student trying to figure out what fossil shrews were eating. It turns out the fossil record of shrews is full of oddballs, so I’m looking at their modern diversity to inform what fossil forms might have been doing. Shrew related antics ensue!

If you created any artwork based on our recent study on Diplodocus color patterns, we would love to see it!!! Please feel free to reply to this with your colorful dippy art 🦕🖌️🎨

NEW paper out today in Royal Society Open Science: “Fossilized melanosomes reveal colour patterning of a sauropod dinosaur” (2025). 🦕

Research conducted in part & facilitated by Elevation Science.

Super cool stuff!! Tess has put a massive amount of work into this project, and the end result is really incredible. Certainly worth a read, and major congrats to @tessasaurus.bsky.social and the rest of the team!
Excited to announce that my second manuscript, “Fossilised Melanosomes Reveal Colour Patterning in A Sauropod Dinosaur” has been published in
@royalsociety.org !! Diplodocus scales are complex and diverse, and it turns out their color patterning was even more so. A 🧵🦕 1/26

While the paper hasn't come out just yet, the news certainly has. Proud to announce our discovery of color patterning in a sauropod dinosaur. Will go in depth tomorrow.

Hey Ben,
The museum is its own separately funded unit, so while this hurts, and directly affects our curators and interns from EAS, UNSM including Ashfall and Trailside remains open and active.

That said, we are gutted. EAS have been allies and partners with the museum for a hundred years. No more.

It's over.

Despite the fact that the academic council recommended against it, despite the fact that the program brought in more tuition than it cost, and despite the fact that Nebraskans need & deserve this expertise, Earth & Atmospheric Sciences will be cut.

BREAKING: ‘This hurts’: UNL eliminates 4 programs despite faculty, student pleas
The University of Nebraska-Lincoln eliminates the Earth and atmospheric sciences 8-0, educational administration 7-1, statistics 7-1, textiles, merchandising and fashion design 7-1 programs.

From all the paleoart and media depictions, one would think Nanotyrannus’s only interaction with the rest of the ecosystem was to harass juvenile Tyrannosaurus rex. Ecologically specialized to be a schoolyard bully

New research on a hot topic -

histology of the holotype supports Nanotyrannus as distinct from T. rex.

While birds and bats both developed adaptations for flight, the way they went about it is so fundamentally different it affects their possible ecological adaptation. Specifically, birds can easily shift to a walking lifestyle, bats can't. 🧪

OK, soooo at some point in the future we'll start talking about the animals and sequences that were considered for #PrehistoricPlanetIceAge but didn't make it over all the hurdles. We're talking giant lemurs, deinotheres, paranthropines, additional cats, zygomaturines and more.

Yes, there was a deliberate push to get rid of all scientific names; of course, I think this is a massive mistake. And, indeed, no roaring for sabretooths, their hyoid anatomy indicates that they couldn't do it :) #PrehistoricPlanetIceAge

Last year I made a Xiphactinus pecan pie for Thanksgiving. What prehistoric fish should I do this year?

Go my Bothriolepis... This year's fish pecan pie! Bothriolepis was a peculiar-looking placoderm from the Devonian period or the Paleozoic. It had two long pointed pectoral fins and silly little eyes on top of its head.

Dinosaurs were nearly wiped out 66 million years ago, long before the start of the Quaternary ice age. However, #PrehistoricPlanetIceAge shows that the few surviving dinosaurs (birds) would go on to become highly successful. Let's meet the ice age dinosaurs featured in the series! 🪶🧪

Bucket list sloth butt selfie!! This beautiful specimen is from Anza Borrego and it has THOUSANDS of in situ osteoderms. There are only two specimens with in situ osteoderms (that I know of) in North America and I’m spending the day with this one.

“Non-functional,” oil on wood panel.
This is the last of the paintings I worked on this summer. It felt nice to let social media take a back seat for a while so I could focus on art without any added pressure.
