Montirictus is an extinct genus of tritylodonts known from the Early CretaceousKuwajima Formation of Japan. It was among the latest surviving tritylodontids, and is closely related to the earlier Xenocretosuchus from mainland Asia, and the JurassicStereognathus 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]
