In Depth

       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.
