invasion of the crocodile-eating snakes!

Scientists recently found bones from a 60-million year old giant snake in Colombia—a snake that weighed a ton, and was as long as a school bus.

Paleontologist Jonathan Bloch of the Florida Museum of Natural History was on the team. He says the find also tells us about climate, because cold-blooded animals depend on ambient heat for their metabolism.

Bloch says it must have been ten degrees hotter in Colombia back then—contrary to a leading theory that tropical climates don’t change as much as others. So today’s warming trend may have an even wider impact than we thought.

Bloch’s team made some other inferences as well. For example, the snake would have been larger than anything else at the time, so it could have easily eaten whatever it liked, including primitive crocodiles!

They also suggest that the extinction of the dinosaurs may have set the stage for this giant snake to become king of the land for millions of years.
