Hupehsuchia

Hupehsuchia is an order of diapsid reptiles, of which Nanchangosauridae is the only family. The order was short-lasting, with a temporal range restricted to the Spathian age of the late Olenekian, spanning only a few million years of the Early Triassic. The order gets its name from Hubei Province, China, from which many specimens have been found.
