The generic name, Crocodylus, was proposed by Josephus Nicolaus Laurenti in 1768. [2] Crocodylus contains 13–14 extant (living) species and 5 extinct species. There are additional extinct species attributed to the genus Crocodylus that studies have shown no longer belong, although they have not yet been reassigned to new genera.
