Re: Re: Synapsids are NOT reptiles!

even try to combine the other "apsids?" If so, how?
Synapsida + Sauropsida has a long, honored, and very appropriate name:
All taxa closer to lepidosaurs and archosaurs than to turtles are Diapsida.
All taxa closer to turtles than to lepidosaurs and archosaurs are Anapsida.
I don't know if the Sauropterygia folk still use Euryapsida: I think some do.
