I didn't even know the Americas had crocodiles before maybe twenty years ago. I thought we had alligators. Here, now, explains how we got crocs.
American crocodiles came from west Africa. This was before five million years ago; but after the Atlantic opened, which split American archosaurs from Old World.
They're going with SEVEN million years. That's impressive raftin'. More impressive even than the journey the platyrrhine monkeys made.
