A pair of beautiful Carboniferous tetrapod skulls on display at the University of Kansas Natural History Museum for #FossilFriday

Three-dimensional skull of Greererpeton in three-quarters view. The bones of the skull bear remarkably prominent ornament.

It’s extremely rare to find an entire skeleton of a fossil amphibian. But that’s what this is – except for a few missing pieces of the hands and feet and the very tip of the tail. #novascotia #fossilfriday

Interesting use of lithium isotopes to test for habitat specialization in Miguasha vertebrates. Notably, the authors find evidence for marine occupancy for tetrapodamorphs Eusthenopteron and Elpistostege, compared to freshwater occupancy in other common taxa.

Chameleons & salamanders evolved a sliding-based linear actuator to launch the tongue via muscular squeezing of a tapered skeletal rod, contrasting with tendon-driven pulling mechanisms common in most musculoskeletal systems, allowing acceleration along a straight path.

Excited to share the first paper from my PhD!

We looked at what traits help Aneides salamanders excel at climbing using museum specimens, CT scans, SEM, and more! No claws or toe pads, so how do they do it? In short, with long limbs, big feet and grippy toes! 🦎🧪

🚨 REPTILE ALERT 🦎🐍🐢🐊🦉
The backbone of @semifossorial.bsky.social's PhD in my lab is finally out after literally *years* in review, and it's a doozy.

Using synchrotron micro-CT scans of MANY amniotes and Paleozoic reptiles we completely restructure the reptile stem lineage across the Permian. 🤩

Xavier Jenkins @semifossorial.bsky.social · Aug 28

It’s finally out!

Our work addressing the origins of reptiles is published in PCJ! peercommunityjournal.org/articles/10....

We use novel info gleaned from the scan data of dozens of stem reptiles to substantially revise our understanding of early reptile evolution #paleontology #herpetology

An ephemeropteran, or mayfly. In Germany, we say ‘Eintagsfliege’ (one-day fly). May-be because it wasn't very careful with its wishes: "Just one day in the Permian, only one day!!"

An awesome study. PETM as a turnover/heterochrony pulse and the modulator of developmental modes in salamanders in the post-event world.
More to the ideas of Elisabeth Vrba on taxonomic turnovers and developmental overturns.

Eophrynus prestvicii, the Coseley Spider, is an extremely well-preserved, 300-million-year-old #arachnid discovered near Dudley. Though it looks like modern #spiders, it was unable to spin a web, instead catching prey using powerful jaws!

Now introducing Amenoyengi mpunduensis ('many-tooth from Mpundu'), a small moradisaurine captorhinid from the late Permian of Zambia with multiple rows of teeth! #Permian #Paleontology 😄

Photos of a skull of a captorhinid in standard anatomical views. The skull is preserved in a brownish red mudstone and is badly weathered, but the internal anatomy is well-preserved.
