This is my entry for @paleopinesofficial's rock painting competition. Say hello to Rocky the Desma! Rocky is made from stones I found in my garden, hand-painted with acrylic paints and some felt for the finishing touches. I had an absolute blast making him.

Here's some progress pictures!

and the end of Perspectives Triassic! This is a part of my Perspectives series, check out #perspectives on my blog for more!

"Placerias Problem" Placerias/Desmatosuchus Triassic, 220 million years ago, Chinle Formation During the Triassic, the continents were all one - this was, of course, the landmass Pangea. The presence of such a massive supercontinent produced an extreme weather effect known as the Pangean megamonsoon - a seasonal wind reversal taking the coasts from arid and dry to incredibly rainy. This is also the cause of the stampede we see here. Placerias was one of the latest-surviving dicynodonts. Having made it straight through the Great Dying, they'd experience a rediversification during the Triassic before dying out by the Jurassic's beginning. Not only did it have actual tusks on the inside of its mouth - it also had two "false" tusks on its beak - known as maxillary caniniforms! These were sexually dimorphic - longer in males and shorter in females.

Desmatosuchus was an aetosaur - a crocodile relative that died off after the Triassic as well. An armored back and spikes on its sides would have made for an effective defense against any predator, and it likely rooted around for plants and invertebrates in the muddy ground where it lived. Although its low profile might be effective in a predation scenario, however....this is no predation scenario.

A little result from tonights #paleostream. We looked into the diversity of aetosaurs, Triassic tanks that are actually related to crocodiles.

"While battling its prey, a Postosuchus hurls a juvenile armoured aetosaur, Desmatosuchus, high over its back. Desmatosuchus reached lengths of 5 m (16 ft)."
