Morning warmup sketch for I was thinking of this scene where a Pristerognathus (therocephalian) chases a Diictodon (dicynodont) that was caught too far out of its burrow. Permian (Capitanian) of South Africa.

Today on "Dinosaurs!" weirdness, the Permian synapsid Moschops. It didn't make too many appearances in the magazines, but these two (both only credited as National History Museum) stood out to me as particularily derpy.

Congratulapsid, you’re a synapsid!

Started this sketch yesterday of a Gorgonopsid. :3

Drawing underrated prehistoric animals 3/?: Cotylorhynchus, a big synapsid from the Permian era. It’s a very round friend with a tiny little head, and I don’t think this drawing does the teeny tiny head justice…

Only three groups of Synapsids/therapsids survived the end-Permian mass extinction event into the Early Triassic: dicynodonts (top), therocephalians (center), and cynodonts (bottom). Only the latter (our relatives) survived into the Jurassic.

Finished Cotylorhynchus!!! Gave this Early Permian synapsid some cornified pads on the skin to help it dig/burrow, which is what it likely did with those action figure forelimbs it's got.

I is for Ianthasaurus

A mammal like reptile of the animal group Synapsid, one of our earliest common ancestors, for the extinct series.

On this, the eve of St. Patrick's Day, I only want to remind you that our distant relatives, Dimetrodon and Sphenacodon (Permian synapsids) had appropriately-shaped tooth roots in cross-section...

Should have the colour balance issue fixed by next week.

When it’s President’s Day, and you can’t wait to take advantage of all these furniture sales... but also you’re not a dinosaur but rather a “mammal-like synapsid.”

A section through the snout of arguably the cutest little animal to ever go extinct, Diictodon! These tusked, beaked, pug-sized critters from the Permian period belonged to the Synapsida (the group that also includes mammals).

Synapsids are weird but can be pretty spectacular, like this amazing Cotylorhynchus
