It is certainly NOT a true lizard. Beyond that, it has been
difficult to place properly. I think it is now considered
an archosauromorph, as you say.
The rhynchosaurs are a seperate group from the rhynchocephalians
(the order containing the tuatara), and are indeed archosauromorphs.
[They are also *very* strange animals indeed].
