Cromptodon is an extinct genus of cynodonts from the Triassic of Cerro Bayo de Portrerillos, Cerro de las Cabras Formation, Argentina, South America. It is known only from PVL 3858, a mandible.[1]
The skull has been estimated to have a length of 2.7 centimetres (1.1 in).[2]
The morphology and distribution of the cups on the postcanines is considered to be very similar to Thrinaxodon liorhinus differing in the fact that the cingulum is lingually wider. The coronoid, prearticular and angular processes, Bonaparte considered, were more developed than those in Thrinaxodon, being more similar to Tribolodon (now Bolotridon). The lower postcanines are buccolingually expanded.[3]
