Cynodontosuchus
''Cynodontosuchus'' is an extinct genus of baurusuchid mesoeucrocodylian. Fossils have been found from Argentina of Late Cretaceous age from the Bajo de la Carpa Formation (dating back to the Santonian) as well as the Pichi Picun Leufu Formation (dating back to the Coniacian and Santonian). It was the first non-Cenozoic sebecosuchian to be described, being assigned to the suborder in 1896 by Arthur Smith Woodward. 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.〔Steel, R. (1973). Crocodylia. In: ''Handbuch der Paläoherpetologie. G. Fischer, Stuttgart and Portland'', 16, 116p.〕 It has been proposed several times that the genus is a senior synonym of ''Baurusuchus''.〔Gasparini, Z.B. (1996). Biogeographic evolution of the South American crocodilians. ''München Geowiss. Abh.,'' A(30):159-184.〕 However, it differs from ''Baurusuchus'' in that its rostrum is less deep and has five maxillary teeth.
