I just found out that we're in the same taxonomic suborder (Eupelycosauria) as Dimetrodon and Edaphosaurus. Apparently we're closer to the Dimetrodon, which means that Dimetrodon is more closely related to our Permian ancestors than it is to the Edaphosaurus.

Daphy the Dimetrodon

would probably have trouble vocalising "suffering succotash"... But not quite as much as WE would have disgusing the dorsal sail I seem to recall our ancestor possessing...

I haven't read a book on prehistoric reptiles since i was about eight: so I could be wrong here... lol

Yes, the sail thing is interesting. If two more remotely related reptiles had the sail, then Permian pre-mammal presumably had it also. Must look at the therapsids and cynodonts (successively closer again and more recent - later Permian, I think).
