Dimetrodon concept art

Dimetrodon is a synapsid that lived in the Permian period. It is smaller then the Gorgonpsid. It was supposed to appear in The Great Dying, but was scrapped because there is already 2 carnivorous synapsids.

What could have beenEdit

Dimetrodon would have hunted Lystrosaurus and Dicynodon, but that would be twice the amount of carnivores then herbivores (also note that Dimetrodon actually lived earlier than the end-Permian).
