Dimetrodon Rough Sketch121 viewsAbout thermoregulation theories in Dimetrodon: heating up the animal and retaining heat in a large animal would be easier without the fin. In modern mammals, the only nearly analogous thermoregulator is on the African elephant (the ear), and that's to dump heat. Other animals that draw heat through fins/wings are either very small or very thin (unable to retain heat). This heat-exchange in a poorly thermoregulated endothermic animal would grow in importance with the animal's size, with younger Dimetrodon's not having as large a "fin" - and that's what one finds in juveniles.

Prehistoric Argentinian Rhino76 viewsUnidentified prehistoric rhinoceros from Argentina. Extrapolative anatomy and habits based on tooth wear, facial feature, extant rhinos, hippopotamus skull anatomy. Speculate it is a wetlands-living aquatic feeding rhino, with habits like that of the moose.

Procynosuchus153 viewsDigital painting (fast) of a procynosuchus posturing. Given the anatomy, long powerful forearms and flattened head, I speculated at a more badger-like pose, with the low-mounted forelimbs splayed as the cheeked face snarls. I figured that with chewing teeth it'd need a pouch to keep it from slobbering all out on the ground, hence the more mammalian mouth... the long scales near the snout are also speculative.

Quick Raptor Sketch80 viewsFast sketch using tablet - 10 minutes.

Simosuchus clarki205 viewsSimosuchus clarki - I picked this one because I'd never seen a snub-nosed crocodile before, I thougtht it would be cute, and I didn't see any renderings of the creature other than skulls, so I thought I'd take a whack at it. The crocodilians are really cool looking, and I might do a few more along these lines.

Suchomimas spp169 viewsThis one is a bit rushed, and so the dino is a bit smooth. A fish-eating dinosaur, I call this estuarine scavenging "Easy pickings."

Tiktaalik roseae71 viewsMy interpretation of this creature- the flat eyes just never sat well with me- as a few frogs I can think of have them- but it would make more sense for a flattened jaw and flexible neck to see things to your sides.

Triceratops90 viewsTen minute sketch - Triceratops. One of my favorites from when I was a kid.
