#FossilFriday flashback: My lab published two major papers this month on 1) dental functional morphology and 2) vertebrate paleontology & paleobiogeography. It made me so proud of the research teams I've been a part of over the past decade, but it also prompted reflection on my academic path (🧵1/5)

Research on the fossil record of mammals in Mexico suggests that the geographic region acted as a biodiversity “holding pen” for 10 million years. Learn more this week in Science: https://scim.ag/4xhNmQ9

Here is @ucberkeleyofficial.bsky.social Bob Sanders' write-up of our Great American Biotic Interchange work: news.berkeley.edu/2026/07/30/n...

North and South America weren’t always connected, but their mammals still found a way to intermingle - Berkeley News

Before the Panamanian land bridge formed about 3 million years ago, mammals on the two continents were isolated — or so biologists thought. New fossils show that they found ways to mix long before tha...

Massive congrats to @tsengzj.bsky.social & colleagues for this new piece of research highlight the role of México as a holding pen for faunal exchanges during the GABI starting 10 mya 😱 www.science.org/doi/10.1126/...

Exhilarated to share a 2nd @science.org cover article this month from our lab @ucberkeleyofficial.bsky.social! A collaboration with US & Mexico colleagues on the role of a Mexican biogeographic holding pen in shaping the Great American Biotic Interchange (GABI)(1/11) www.science.org/doi/10.1126/...

📢 JOB ALERT! 📢 I am recruiting a 30-month postdoc to work on modelling the vision of trilobites @hfspo.bsky.social ! If you like 3D data, fossils, and functional morphology, this is the one for you! 📆Deadline 27. Aug Pls contact me with any Qs and share widely! www.bristol.ac.uk/jobs/find/de...

Excited to share our new paper in Science Advances! Led by Dr Wei Wang at #IVPP in Beijing, it presents a complete skeleton of #Austronaga, the most marine of all archosauromorphs. To boot, this fossil preserves the oldest complete digestive tract of any reptile! www.science.org/doi/10.1126/...
