As a triassic dicynodont once said, "If you're good at something, never do it for free." So I made a coprolitepost and put it on a t-shirt (and other stuff) for you to buy, thereby paying me, just as the prophecy foretold!

Not many vertebrates are known from the Late Triassic Norian stage in Western North America: Shastasaurus (or Shonisaurus) sikkaniensis from the Pardonet formation of British Columbia was the largest marine reptile ever found. Gunakadeit was an odd thalattosaur from Alaska.

One of the partial results of my post-doc work, using photometry/computer tomography and 3d modeling software to reconstruct damaged fossil specimens, in this case the skull of Pagosvenator candelariensis, an erpetosuchid from the Triassic of Southern Brazil.

Honestly a lot of triassic reptiles fit the retrosaur aesthetic.

Postosuchus looks a lot like a retro rex for example.

I feel like the only niche we dont seen replicated fully in Triassic Archosaurs is the fact that other than Shringasaurus which was more of a sauropod analogue than a Ceratopsian analogue. No real ceratopsian convergent form in Triassic archosaurs, but I hope it existed

Oops. Last tweet had the wrong species. A flock of Arcticodactylus in the Late Triassic. A little update to a piece from 2020 (WIP)

Triassic Archosaurs are just so unique considering the convergent evolution that would later be taken by their dinosaurian relatives in the later Jurassic and Cretaceous. What catches my eye is just the diversification into familiar yet bizarre forms of life. Their all so unique.

On a Late Triassic afternoon, a large ichthyosaur lazily drifts into a shallower bay on its side to be pampered by local fish and early pterosaurs, who peck at dead skin, bits of food and ectoparasites.
