Hypsognathus fenneri Gilmore, 1928

Phylum: Chordata Haeckel, 1874

Subphylum: Vertebrata Cuvier, 1812

Classe: Reptilia Laurenti, 1768

Ordine: Procolophonomorpha Romer, 1964

Famiglia: Procolophonidae Seeley, 1888

Genere: Hypsognathus Gilmore, 1928

Descrizione

Varie caratteristiche di questo tardo rappresentante della famiglia indicano che esso era erbivoro e poco agile, dato il corpo grosso e tozzo. I molari dall'ampia superficie erano adatti a triturare vegetali coriacei. Le spine ossee ai lati del capo costituivano probabilmente una buona difesa contro i predatori come i contemporanei podokesauri (dinosauri carnivori).

Diffusione

Rettile anapside della famiglia dei Procolofonidi, vissuto in America settentrionale (New Jersey) nel Triassico superiore, che poteva raggiungere una lunghezza di 33 cm.
