🚨 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.

Mosaic anatomy in an early fossil squamate - Nature

Breugnathair elgolensis gen. et sp. nov., an early squamate identified from a newly discovered Middle Jurassic skeleton on the Isle of Skye, provides new evidence on the origins of snakes.

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 🩻☢️🦴

Text that reads: The University of Texas High-Resolution X-ray CT Facility (UTCT) will host a short course on the fundamentals of acquisition, visualization, and analysis of high-resolution X-ray CT (HRXCT) data for biological and paleontological specimens June 2-4, 2025 in Austin, TX.
This short course will present an overview of the acquisition, interpretation, 3D visualization and analysis of HRXCT data. This will be followed by hands-on training focused on 3D visualization, surface extraction, and segmentation (e.g., endocasts, digital dissection) including deep learning. Covered programs include ImageJ, Dragonfly, and 3D Slicer/SlicerMorph.
This course is sponsored in part by NSF and funds are available to help cover the cost of travel, lodging, and meals. There is no charge to attend. Because we will not be able to accept all applicants, preference will be given to those who have/will have HRXCT data for the course and have a demonstrated need for immediate application of the skills learned. Students and early-career researchers receive priority. Participants are invited to bring their own HRXCT data, or to have specimens scanned (at a significant discount) at UTCT prior to the course.

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 🎨🖼️

I am installing the life size 3D printed dicynodont skeleton on display in the Field Museum Grainger Science Hub. Grey bones represent real fossils from the bonebed, blue bones are resized or reflected bones.

The fossil dicynodont skull in a plaster cradle custom made for the display. In the background are shin bones that I thin sectioned to tell us information on how old these animals were when they died around 240 million years ago

Augmented reality of a dicynodont skeleton in Stanley Field Hall.

A reconstruction of Dolichuranus in the river beds of what is now Tanzania some 240 million years ago. Image credit to Mark Witton who is thanked for this artistic reconstruction.

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.

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 👀

The left image is a grey value CT scan of a fossil bone thin section. The right image is the same fossil bone viewed under cross-polarized light microscopy with brightly colored pink, purple, blue, and yellow colors indicating bone mineral fiber orientations. The inside of the bone’s marrow cavity is infilled with brown crystals that look like a geode.

Happy to help! And spread the word that JVP needs submissions to fill volumes. It’s unclear when or if the journal will move to an online format that frees us up from this type of constraint.

Zoe Kulik @paleozoek.bsky.social · Nov 20

I’m a JVP editor & we talked about this at the publications meeting at SVP. The journal had a backlog but as of today, the pace of finishing volumes is dependent on copy flow. I don’t know what caused the backlog, but JVP now needs submissions to fill volumes so the long lead times should be over.

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 🤩 🐭🐹🐿️

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!
