Sphenosuchus is an extinct genus of Crocodylomorpha from the Elliot Formation (Early Jurassic) of South Africa, discovered and described early in the 20th century. The skull is excellently preserved but other than elements of the forelimb and isolated parts of the hind limb, the Sphenosuchus material is incomplete. It was probably quadrupedal, but may have been a facultative biped.
