Fossil representation: Many individuals.

       Dyrosaurus was a long snouted crocodile that had jaws filled with numerous,‭ ‬thin recurved teeth.‭ ‬These kinds of teeth are indicative of a piscivorous‭ (‬fish eating‭) ‬lifestyle.‭ ‬At up to six meters long,‭ ‬Dyrosaurus were large when compared to modern crocodiles,‭ ‬though positively tiny when compared to some North African Mesozoic crocodiles like Aegisuchus,‭ ‬and Sarcosuchus.‭ ‬Dyrosaurus however managed to survive the KT extinction sixty-five million years ago,‭ ‬and the genus continued to be present in North Africa till the Eocene.
       Care should be taken not to confuse Dyrosaurus with the similarly named ornithopod dinosaur Dryosaurus.
