How did reptilian things that looked something like crocodiles get to the Caribbean islands from South America millions of years ago? They probably walked.
The existence of any prehistoric apex predators in the islands of the Caribbean used to be doubted.

While sebecids first emerged during the Cretaceous, this is the first evidence of them lurking outside South America during the Cenozoic epoch, which began 66 million years ago. An international team of researchers has found that these creatures would stalk and hunt in the Caribbean islands millions of years after similar predators went extinct on the South American mainland. Lower sea levels back then could have exposed enough land to walk across.
