Very excited that our paper about ichnofossils in ungulates from La Venta is finally out today in @jvertpaleo.bsky.social. This has been several years of work from colleagues around the world, including @jwmorenob.bsky.social and many others, and with fantastic art by @literallymiguel.bsky.social

My art for @therhinoscaros.bsky.social and colleages!, who reviewed different lines of ichnological evidence in the form of bitemarks from both semiaquatic and terrestrial suchians on Colombian mammals :3 (my Puru art to the right is rather old/outdated lol, sorry about that) link below!👇

A very important open access study (doi.org/10.1016/j.cub.…) led by @semifossorial.bsky.social on the ancestry of turtles was published! Eunotosaurus' similarities are just a case of evolutionary convergence, & pantestudines might have a close relationship to sauropterygians within archosauromorpha

Pangolins possess a spectacular, dense network of diploic veins for brain drainage! In our latest study, we show that this pattern may also provide rare morphological evidence linking pangolins and carnivorans in the Ferae clade. Check it out here: academic.oup.com/zoolinnean/a...

Tooth structure isn’t always a good indicator of diet in ancient animals
Extinct South American pachyrukhines were mammals with tall teeth thought to be optimized for grazing. They probably looked a lot like these modern maras. Image credit: Shutterstock/Mariano Jedrzejews...

Ever-growing teeth ≠ grass diet! New study on pachyrukhine notoungulates, rodent-like fossil mammals from Argentina, shows they were mainly fruit & seed eaters! #Paleontology #fossils @societyofvertpaleo.bsky.social @paleosoc.bsky.social @oupaleobiology.bsky.social 10.1016/j.palaeo.2026.113585

New paper out today! "Fossil otolith assemblages reveal millennial-scale changes in reef fish biomass and trophic structure across the Isthmus of Panama" 🔓https://doi.org/10.1098/rstb.2024.0419 We used fossil fish otoliths to reconstruct community structure and energetics over millennia.

Right on time for #FossilFriday my lattest article is now online! 🎉 doi.org/10.1111/joa.... We propose a standardized methodological framework to study enamel histology in extinct species and identifiy enamel increments correctly, step by step.
