†Archaeovenator hamiltonensis
Reisz and Dilkes, 2003
—
Conservation Status:
Extinct
Diagnosis:
Small varanopid eupelycosaur characterized by the
presence of a large medial process of the postorbital that underlies
the parietal and large nasal process of the premaxilla
that forms a broad, expanded posterodorsal process. Differs
from other varanopids in having simple conical, slightly
recurved teeth, lacking maxillary dorsal process, lacking a
lateral boss on the postorbital, and lacking excavation on the
neural spines and arches.
Distribution:
Known only from the type locality.
