Now that you mention it, it WAS a polyphyletic trash-can. The Thecodontia became a receptacle for any Triassic reptile that appeared to be an archosaur and did not appear to be a dinosaur, crocodilian or pterosaur. I've seen _Longisquama_, _Sharovipteryx_ (_Podopteryx_) and _Hupehsuchus_ all shoehorned into the Thecodontia. For the most part the Thecodontia was a paraphyletic waste-basket, but its membership became so broad and ill-defined that it occasionally the Thecodontia did become polyphyletic.

Come back Dr Holtz, all is forgiven!!!
