This page is about Crocodylomorpha as a whole, from the Early .
Triassic to present genuses. They are here referred to as crocodilians for simplicity
Crocodilians are a long-lived group of reptiles, occassionally marine, with an almost cosmopolitan range. First evolving in the Triassic, they survived the K-T Extinction into the Holocene.
List of crocodilians Edit
True crocodilians Edit
True crocodiles are the most numerous of the true crocodilians. They include
African Nile crocodiles, mugger crocodiles, and the slightly larger Australian saltwater crocodiles.
Alligators are more robust than true crocodiles, with a less diverse range. They include the largest crocodilian of all time, the Late
Marine crocodilians Edit
Marine crocodilians were crocodilians that took to the sea, mostly during the
Jurassic. Metriorynchus was a small marine crocodilian from England.
Early crocodilians Edit
The first crocodylomorphs lived in the
Triassic; true crocodilians evolved in the Early Cretaceous. Triassic crocodilomorphs included Proterosuchus; Early Cretaceous crododilians included Sarcosuchus, which rivalled Deinosuchus in size.
