Earlier we looked at the skull of Priosphenodon (aka Kaikaifilusaurus) No dorsal or occipital views, but plenty of data to nest it at the base of the rhynchosaurs, despite its identification as a rhynchocephalian (sphenodontian).
Now (Fig. 1), courtesy of Dr. Sebastián Apesteguía (Argentina), who wrote his thesis on Priosphenodon, an image of the skeleton as a museum model is available. I understand that the carpals are among the few imagined parts here.
the wide, bulging cheeks and extremely narrow parietal (skull roof), as in rhynchosaurs. The nares had not become confluent. That comes in more highly derived forms. But look at those twin anterior dentary tips, as in rhynchosaurs. No anterior process on the ilium though. Stance probably not as sprawling as this, and not as erect as in rhyncosaurs.
