"Scientists say they have discovered fossil remains of a colossal prehistoric snake that once roamed the superheated Paleocene jungles of South America. The one-tonne Titanoboa cerrejonensis would have been more than 40 feet long and ten feet around at its thickest.
"Investigating brainboxes say the mighty snake's huge size was made possible by the significantly higher temperatures on Earth 60m years ago. The size of cold-blooded creatures such as snakes is limited by the warmth of their environment."
That's a big snake!
(thanks muzadi!)
