It’s so here’s a…

Wait a minute. That’s not a whale!

This is a giant ichthyosaur. Ichthyosaurs were the first truly gigantic animals to evolve. The largest skeleton is 21 metres long and belongs to the Triassic species, Shonisaurus sikanniensis.

Work in progess: a possible solution to yesterday’s problem fitting Coelophysis - a Triassic predatory dinosaur - in a frame. The proportions still need another check, but I like his cheeky expression.

Originally, I had planned to hopefully do 2 books. The first one about the tetrapods of the Triassic and Jurassic, and the second one about the Cretaceous. However, as I have worked on it, the first book has become humongous!

Today’s is Poposaurus gracilis Mehl 1915 from the Upper Triassic of the western US. Poposaurus has a remarkably similar body plan to dinosaurs, yet has hallmarks of all pseudosuchians. We know almost the full anatomy, minus parts of the skull

Reading A New History of Life by Ward and Kirschvink. Was unaware that low oxygen levels correlate with increased disparity, while high oxygen levels correlate with increased diversity. Hence the high disparity of the Cambrian and Triassic.

Today’s is Desmatosuchus spurensis Case 1921, an aetosaur from the southwest. It was a one of the largest with shoulders spikes measuring ~50 cm. The diet is his unknown, but it could have been the largest herbivore of NA in the L Triassic

F is for Fasolasuchus (B in this pic), a very distant croc-relative from the Triassic of Argentina. It’s in a messy part of the tree we sometimes lump together and call “Rauisuchians.”

Ecstatic to be illustrating this amazing book series! The first four books out MAY 2021! Here is the preliminary Lisowicia for the, you guessed it, Lisowicia book (book 4). Lisowicia is a Late Triassic dicynodont (a distant relative of ours) https://t.co/4W3dWC5dO2

The Triassic sure was full of weird critters.

Hyperodapedon looked like a huge herbivorous tuatara, but was in fact more closely related to dinosaurs and crocs. I gave it a generous amount of soft tissue including ’lips’ and a gecko-like fat tail.
