Cynodontosuchus was the first non-Cenozoicsebecosuchian to be described, being assigned to the suborder in 1896 by Arthur Smith Woodward.[1] It was described on the basis of an incomplete snout and articulated lower jaw. The presence of a large saber-like second maxillary tooth and a diastema between the maxilla and premaxilla that made room for a large mandibular tooth suggests that Cynodontosuchus is a member of the family Baurusuchidae.[2] It has been proposed several times that the genus is a senior synonym of Baurusuchus.[3][4] However, it differs from Baurusuchus in that its rostrum is less deep and has five maxillary teeth.[5]
