Prehistoric Models: Rhynchosauria

Rhynchosauria is a classification for rhynchosaurs are a group of extinct herbivorous Triassic archosauromorpha meaning “ruling reptile forms” in Greek, is a clade of diapsid reptiles containing all reptiles more closely related to archosaurs. Archosaurs include crocodilians, dinosaurs, and birds (avian dinosaurs), rather than lepidosaurus including snakes, lizards, and tuataras.

Rhynchosaurs first appear in the Early Triassic and reach their broadest abundance and a global distribution during the Carnian stage of the Late Triassic Period. The group is distinguished by their elongated beaks and triangular skulls.
