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), the Pichi Picun Leufu Formation (dating back to the Coniacian and Santonian). the Tiupampan Santa Lucía Formation of Bolivia.

Description

Cynodontosuchus was the first non-Cenozoic sebecosuchian to be described, being assigned to the suborder in 1896 by Arthur Smith Woodward.{{cite journal | last1 = Woodward | first1 = AS. | year = 1896 | title = On Two Mesozoic Crocodilians Notosuchus (Genus Novum) and Cynodontosuchus (Genus Novum) from the Red Sandstone of the Territory of Neuquen (Argentine Republic) | journal = Anales del Museo de la Plata, Paleontologia Argentina | volume = 6 | pages = 1–20 }} 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.
