Titanoboa, the serpent from hell
This is the freakiest snake that ever lived:
Titanoboa was at least 43 feet long, weighed 2,500 pounds (1,140 kg) and its massive body was at least 3 feet (1 meter) wide, they wrote in the journal Nature.
It lived 58 million to 60 million years ago, when Earth's animal kingdom was still recovering from the mass extinction that doomed the dinosaurs and many other creatures 65 million years ago when an asteroid hit near the Yucatan coast of Mexico (Reuters via Yahoo!).
