For #FossilFriday, I thought I’d share my paper published earlier this year on the #macroevolution of carnivorous non-mammalian synapsids: www.nature.com/articles/s42...
May be of interest if you’re curious about the feeding morphology & ecology of Permian predators like Inostrancevia & Dimetrodon

Presenting a skull of the #dicynodont, Ischigualastia, at the BYU Museum of Paleontology in Provo, Utah 🇺🇸 for this #FossilFriday. This ancient, beaked herbivore was the size of a cow & lived in Argentina 🇦🇷 during the Late #Triassic (~230 Ma).

I need a mood booster, let's talk about capybaras.
Here's a capy demonstrating one of MANY ways they can move through the water: running along the bottom.
They're 'semi-aquatic' mammals, just like hippos, seals & beavers. They LOVE water.

Selected species of Dimetrodon.
Here are various sketches showing some species of Dimetrodon, which was a quite diverse genus during the Early Permian. The genus includes about a dozen of species
