    Alligators and crocodiles are some of the oldest and most successful predators on the planet. They date back to the time of the dinosaurs. “Proto-crocodiles” appeared in the Triassic and Jurassic period, although their legs were much different from modern crocs’:

    More modern-looking, “true” crocodiles appeared in the Cretaceous period, about 200 million years ago.  Somehow -and no one’s sure why- crocodiles and alligators lived through what killed the dinosaurs and continue to flourish today.
