Ancient sloths ranged in size from tiny climbers to ground-dwelling giants. Now, researchers report in Science that this body size diversity was largely shaped by sloths’ habitats, and that these animals’ precipitous decline was likely a result of increasing human pressures.

Another great figure created with the assistance of #Rstats #phytools, this one by Juan Olvido Perea García et al. "Look past the cooperative eye hypothesis: reconsidering the evolution of human eye appearance." Check out the article here: doi.org/10.1111/brv.70….

Caecilians are a little-known group of ~220 limbless, mostly tropical amphibians. Despite unique vertebrae and skull morphology, their postcranial anatomy remains poorly studied. Santos et al. offer detailed overview and propose unified terminology: anatomypubs.onlinelibrary.wiley.com/doi/10.1002/ar…

The skull & jaws of a big #Tylosaurus we collected in 2021 is all finished! Exquisite details in this toothy mosasaur specimen. The team is making a 2-piece, fiberglass-reinforced storage cradle for it now, and then off to the Perot Museum collections racks. #FossilFriday

A study (involving our Phil Cox) in #rabbits & #hares, found that those adapted for #running have greater facial tilt & simpler #skull #joints versus those with #scrambling or #hopping-based locomotion, which could help with hinge-like mobility. onlinelibrary.wiley.com/doi/full/10.11… UCL
