Because I APPARENTLY want to suffer I’ve chosen four different sail-backed synapsids to include in this series. The first is Edaphosaurus, specifically Edaphosaurus cruciger.
Edaphosaurus is one of the earliest known large herbivorous tetrapods (four-limbed land vertebrates.) A number of synapsids from the early Permian had similar bony sails on their backs, but Edaphosaurus was unique in that it had supportive cross-bars on the spines, and little spikes possibly sticking out on either side (this could have also been covered by skin.) It had a small, triangular head, with muscular jaws fit for cropping away at tough plants.

So, to start the new year on a productive note (well, it may already be the second farther east, but it’s still January 1 here in L.A.), yet another character from the project I’ve been posting about. Let’s see if I can post more regularly this year than I did the last.
