Researchers have found fossils of the world's biggest snake ever from northeastern Colombia, a behemoth that stretched 42 to 45 feet long, reaching more than 2,500 pounds from nose to tail tip.

It's the biggest snake the world has ever known, said Jason Head, a paleontologist at the University of Toronto Mississauga and part of an international team who discovered and identified the snake bones.

Forget the snake that tried to eat Jennifer Lopez in the movie 'Anaconda' is not as big as the one we found, Head said.

This thing weighs more than a bison and is longer than a city bus, enthused snake expert Jack Conrad of the American Museum of Natural History in New York, who was familiar with the findings.

It could easily eat something the size of a cow. A human would just be toast immediately.

The discoverers of the snake called Titanoboa cerrejonensis (ty-TAN-o-BO-ah sare-ah-HONE-en-siss). That means titanic boa from Cerrejon Coal Mine, the region where it was found.

It behaved more like an anaconda and spent most of its time in water, and relates to modern boas. It could slither on land as well as swim, Head said. The discovery is detailed on the Feb. 5 issue of the journal Nature.
