Crocodilia
Filozoa
Crocodilia (or Crocodylia) is an order of large reptiles that appeared about 84 million years ago in the late Cretaceous Period (Campanian stage). They are the closest living relatives of birds, as the two groups are the only known survivors of the Archosauria. Members of the crocodilian total group, the clade Crurotarsi, appeared about 220 million years ago in the Triassic Period and exhibited a wide diversity of forms during the Mesozoic Era.
Although the term 'crocodiles' is sometimes used to refer to alligators, caiman, and gharials, or even to their distant prehistoric relatives the marine crocodiles, a less ambiguous vernacular term for this group is 'crocodilians'.
