Heterodontosuchus is a dubious genus of extinct phytosaur. The genus was first described from a fragmentary anterior section of the mandible found from the Henry Mountains in southeastern Utah, USA. More fossils were later found from Arizona.[1] The name Heterodontosuchus refers to the difference in size between anterior and posterior teeth on this mandible.[2] The teeth were compressed antero-posteriorly spaced closely together.[3] The genus is now thought to be synonymous with Nicrosaurus, and the type and only species, H. ganei, is regarded as a nomen dubium due to the fragmentary nature of the remains associated with it.
