Mormosaurus ("Mormo's Lizard") is an extinct genus of tapinocephalid dinocephalian therapsid from the Guadalupian epoch of South Africa. It was first named by Watson in 1914, and contains one species, M. seeleyi. Members of Mormosaurus had a long skull. Its taxonomic status is not settled, as some authorities synonymize it with Keratocephalus.
