A funky-looking Chambered Nautilus is making an appearance for this week's

What this guy lacks in memory, he more than makes up for with 90 tentacles and a shell that inspires many mathematical debates.

It may be slow, but at least it's more predictable than wind travel.

Spinosuchus was probably similar in size to Trilophosaurus, although as you can see its tall neural spines give its back a raised hump/sail and less of the lean, iguana-like silhouette.

Therocephalians are another group of therapsids that made it into the Triassic. They were probably distributed throughout Pangea during the Early Triassic. One genus (Moschorhinus) is believed to have survived the Permian extinction

For I am opening a thread about Early Triassic tetrapod faunal assemblages. After the Permian extinction, terrestrial faunal assemblages were depauperate and most were very similar in composition. Temnospondyls were quick to diversify

For the coloration, I looked at a bunch of arboreal reptile species, large and small. It's harder than I thought to give it the loose, splotchy look of reptile coloration without losing the semblance of an actual pattern.
