Crocodile Ancestors

Scientists are now discovering the earliest ancient crocodiles by tracing one branch of the vast tree of life 230 million years into the geologic period called the Triassic. There is little about the planet of the Triassic that humans would recognize. The continents we know today had not yet formed and were all contained in one huge land mass surrounded by water, called Pangaea. It was here, along with the dinosaurs, that the first crocs evolved. And they looked nothing like the crocs alive today.
