Is crocodile a descendant of dinosaurs?
Crocodiles Chickens may be the rightful descendants of dinosaurs, but we also know that crocodilians like crocodiles and alligators share common ancestors with dinosaurs too.
Alligators are not dinosaurs, though they belong to the same order as dinosaurs once did. Their ancestors were closely related to dinosaurs and walked the earth at the same time. While dinosaurs went extinct, alligator ancestors went on to evolve into the alligators we see on Earth today.
How are alligators and crocodiles related to dinosaurs?
Crocodilians (including alligators) are also not directly descended from dinosaurs. Alligators and dinosaurs are both archosaurs, therefore alligators (and other crocodilians, such as crocodiles and caimans) are the closest living (non-avian) relatives of dinosaurs.
Reptiles, such as crocodiles and lizards, have legs that sprawl out to the side. Their thigh bones are almost parallel to the ground. They walk and run with a side-to-side motion. Dinosaurs, on the other hand, stand with their legs positioned directly under their bodies.
