Science Art: Cotylorhynchus, by Nix


The Tumblr illustrator Nix is having a paleoart February, creating a new illustration of a non-dinosaur, non-pterosaur prehistoric creature every day of the month.

This is the seventh entry, a caseasaur named Cotylorhynchus. It might look like a salamander, but could weigh nearly 4,500 pounds and measured up to 20 feet long.

They ate plants, but nobody messed with them. 275 million years ago, they were an apex herbivore.
