Montirictus is an extinct genus of tritylodonts known from the Early Cretaceous Kuwajima Formation of Japan. It is currently the latest surviving tritylodontid species, and is closely related to the earlier Xenocretosuchus from mainland Asia, and the Jurassic Stereognathus from the UK.[1] It may be a species of the genus Stereognathus,[2] but resolution of its affinities conditions upon the discovery of additional material.[3]
