I’ve always had a huge soft spot for “small” ornithischians so here’s a quick dryosaurus

I've been seeing this image from the recent ornithischian paper and I can't help but be disturbed by the edmontosaurus. All the other ornithischians look goofy when facing forward but the forward-facing edmontosaurus is genuinely the most terrified I've ever been of a dinosaur.

My memory theropods aren't that far off. This means I should draw some more ornithischians from memory and see how wrong I can truly be.

We got two talks at that outlined the various ways that small ornithischians could beat you in a street fight.

Congrats to and for their awesome talks. Very excited to see where this research goes.

Adding some smallish bipedal ornithischians to the mix was a must and Thescelosaurus with well known osteology and interesting skull shape was a obvious pick (also gives the T. rex something to eat)

First ornithischians or non-dinosaurian dinosauriforms? Silesaurus (top) and Lewisuchus (bottom)

By the way, I do not think “silesaurids” (including Pisanosaurus) are jerks but AMAZING animals that were much more interesting than many ornithischians that came afterwards 🙊🙊🙊

Started updating something new this morning. Not enough ornithischians on my feed yet.

Every day I draw more ornithischians

Turn up brightness to see all details I guess

Ornithischians breathed a bit like crocodiles, in that muscles originating on the pelvic girdle pulled on the thoracic peritoneum to generate negative pressure and draw in air (unlike us mammals, who use a diaphragm attached to the ribs to do the same). 🎨 from paper.

I hope that the data contained herein will be a useful springboard for future phylogenetic and paleobiological studies of early-diverging ornithischians.

In short, it explains that, although ornithischians likely DID NOT have a "new cheek muscle" bridging between maxilla & dentary, some (but not all!) of them, like ceratopsids, had jaw muscles originating inside the head that likely extended forward on the jaw for more leverage.

Many of Dixon's smaller ornithischians would hold up pretty well today if it wasn't for that weird fashion of shrinking the tail muscles to a level it's almost just a stiff rod.

There IS precedent for this kind of flexibility as it’s seen in alligators but im not sure about ornithischians or other archosaurs

A late post, but I sketched some theropods tonight; no references so their accuracy is dubious, but I wanted to have fun ^^

A large theropod from the Elliot Formation, Dracovenator regenti lived in the early jurassic of South Africa being a major predator of the varied herbivores that existed in the region, including small sauropodomorphs and the minuscule ornithischians.
