When they split from each other, they formed two major evolutionary pathways: the bird-line archosaurs, which also includes all dinosaurs, and the crocodile . . Split off into pre-historic crocodiles and early dinosaurs. One branch evolved into dinosaurs and birds and the other branch gave us the crocodiles and alligators we know today, plus a host of now-extinct relatives. When they split from each other, they formed two major evolutionary pathways: the bird-line archosaurs, which also includes all dinosaurs, and the crocodile . Erpetosuchus and Doswellia are two leading candidates for the honorific of "first crocodile," though the exact evolutionary relationships of these early archosaurs are still uncertain. The fossils belonging to Carnufex also come from North Carolina, and were first discovered in 2003. Stomatosuchus was one of the older beasts. This crocodile ancestor discovered in Wyoming shows how it became the predator it is today.

Sail on it's back. A good example is Terrestrisuchus, a tiny, long-limbed crocodile ancestor that may well have spent much of its time running on two or four legs (hence its informal nickname, the greyhound of the Triassic period). Careful taxonomic work supports the theory that this creature, commonly called the 'shield croc,' was the common ancestor. who date back to the Early Triassic period (250 million years ago).
