Classification: Chordata,‭ ‬Reptilia,‭ ‬Crocodylomorpha,‭ ‬Notosuchia,‭ ‬Sebecosuchia.
Species: C.‭ ‬rothi‭ (‬type‭)‬.
Diet: Carnivore.
Size: Uncertain due to lack of remains.
Known locations: Argentina‭ ‬-‭ ‬Bajo de la Carpa Formation.

Fossil representation: Partial skull‭ (‬mostly of snout,‭ ‬maxilla and premaxilla‭) ‬as well as partial dentary‭ (‬lower jaw‭)‬.

       When named in‭ ‬1896,‭ ‬Cynodontosuchus was not only the earliest known sebecosuchian crocodile,‭ ‬it was also the first confirmed as living before the‭ ‬Cenozoic period.‭ ‬Since this time there are now several Cretaceous sebecosuchian crocodiles known to us,‭ ‬and one of these genera,‭ ‬Baurusuchus,‭ ‬has been proposed by some to be a junior synonym to Cynodontosuchus.‭ ‬Critics of this theory however point out that Cynodontosuchus has a much deeper rostrum that Baurusuchus,‭ ‬as well as only five pairs of teeth in the maxilla,‭ ‬significantly less than Baurusuchus.
