These and many other types of ancient reptiles are often wrongly called dinosaurs. Marine reptiles, such as ichthyosaurs, plesiosaurs and mosasaurs are not dinosaurs.

What dinosaur did alligators evolve from?

About 250 million years ago, the archosaurs split into two groups: a bird-like group that evolved into dinosaurs, birds, and pterosaurs, and a crocodile-like group that includes the alligators and crocs alive today and a diversity of now-extinct relatives.

Alligators and caimans split in North America during the early Tertiary or late Cretaceous (about 53 million to about 65 million years ago).

Did alligators survive the dinosaur extinction?

Crocodiles survived the asteroid strike that wiped out the dinosaurs thanks to their ‘versatile’ and ‘efficient’ body shape, that allowed them to cope with the enormous environmental changes triggered by the impact, according to new research. Crocodiles can thrive in or out of water and live in complete darkness.

Are alligators from prehistoric times?

The first alligator ancestors evolved some 245 million years ago. About 80 million years ago, during the Cretaceous period, crocodilians appeared. This group includes alligatoroids, such as Brachychampsa, as well as their close relatives the crocodiles and caimans.
