Edaphosauridae is a family of mostly large (up to Script error: No such module "convert". or more) Late Carboniferous to Early Permian synapsids. Edaphosaur fossils are so far known only from North America and Europe.

Characteristics

They were the earliest known herbivorous amniotes and, along with the Diadectidae, the earliest known herbivorous tetrapods.[1] The head is small in relation to the bulky body, and there is a tall sail along the back, which may have functioned as a thermoregulatory device.

Classification

The interrelationships of Edaphosauridae was investigated in details by David M. Mazierski and Robert R. Reisz (2010). The cladogram below is modified after their phylogenetic analysis.[2]
