Love dinosaurs? Come chat with past AMNH REU intern Jean at his poster # 539 on the second floor of Hall 3 today! #SVP2025 #2025SVP #dinosaurs #bonehistology

The reality of being a freelancer is that you end up working a lot of evenings and nights, something #mammals have been doing since the Mesozoic. Here's new #paleoart of two #Jurassic gliding Mammaliaformes, Arboroharamiya, starting their day as the sun sets 160 million years ago. #sciart #fossil

🚨New paper alert!🚨 🧪⚒️ Terrestrial gigantism evolved through divergent pathways, with dinosaurs favoring cortical reinforcement while mammals adopted flexible trabecular expansion strategies www.sciencedirect.com/science/arti...

🚨 New 🦎 🚨 Breugnathair (“Bree-ack na-haird”) elgolensis is the oldest and most complete squamate from the Middle Jurassic of Scotland. Its Gaelic name means ‘false snake of Elgol’, referencing the snake-like teeth and jaws but lizard-like body and limb proportions.

A permineralized #Dimetrodon femur ready for #ThinSectionThursday #Paleohistology

Every year UTCT teaches NSF sponsored short courses on high-resolution X-ray CT, taught by UTCT staff (including me!). Applications for the 2025 courses are now open! See below for the biological/paleontological course info, & we also have a geological one. If you'd like to apply, send me a DM 🩻☢️🦴

Happy #FossilFriday A few weeks ago we opened the first exhibit I helped design based on my work on bone histology and taphonomy of a #dicynodont bonebed from Tanzania! If you are passing by the #FieldMuseum, go check out the #GraingerScienceHub Huge thanks to @markwitton.bsky.social for 🎨🖼️

New pub alert! 🚨 and the final installment of papers from my dissertation! Really happy to share this work on Triassic cynodonts that reveals surprising growth differences, helping to reshape our understanding of stem mammal evolution #ThinSectionThursday #Paleontology #Cynodonts #Triassic

Why do bone histologists use the middle of bones when examining growth patterns? Because mid-shaft record the longest history of growth, seen in this tiny femur where the joint ends are made of spongy bone and only the middle shows growth marks.

If you don't know about the @burkemuseum.bsky.social DIG Field School, it's a great time to learn about this PD program for K-12 educators and classrooms www.burkemuseum.org/education/ed... Sign up for a Microfossil Workshop by Jan 3! and the DIG Field School applications open soon! #paleo #K12STEM

New paper alert! This was a fun study examining intraskeletal growth patterns in leopard geckos using fluorescent labeling. Labels administered in ovo are still present up to 4 years post-hatching! doi.org/10.1111/joa....

Our 2025 #REU applications are now open! Come learn with us next summer at the #AMNH! More information can be found www.amnh.org/research/ric...

🚨New Diamond 💎 Open Access Journal in Paleontology 🦴🐚!🚨 Send us your manuscripts 📜 and publish fully open access 🔓 entirely for free! #openacess #paleontology #free #palaeontology #diamond #open

Happy #ThinSectionThursday Here is a side by side comparison of virtual histology from synchrotron tomography on the left and “traditional” histology from optical microscopy on the right. It’s sometimes hard to tell what’s a growth mark in virtual histology but with this, we can can train our 👀

Job alert! Two Full-time Assistant Teaching Professor positions in our Department (UW Biology). Come join us! Please share: apply.interfolio.com/147513

A late night #ThinSectionThursday Resisting that “we’ll pick it up in the new year” mentality with cool collaborations that have data that looks this good

Paleobluesky has risen! So happy to be here and share a sneak peak of some micro-CT scans. Check out the 3D histology of some truly tiny Mesozoic mammal fossils 🤩 🐭🐹🐿️ #fossilfriday #fossil #zeissxradia #amnh #watchthisspace

Come work with us! We are hiring a new #curator in invertebrate paleontology! careers.amnh.org/postings/4301 #academicjobs #tenuretrack #AMNH

#ThinSectionThursday brought to you by this stunning watercolor painting by Leonie Schön. Check out her histology artwork! lamellipodiumart.com

I’m new to this online paleo community and am looking forward to getting connected. If you’re going to #2024SVP next week, stop by my talk on Wed. at 8am in the mammalian life history evolution symposium for a deep dive into 3D bone histology from some of the earliest non-mammalian synapsids!
