Largest prehistoric snake on record discovered in Colombia

Named Titanoboa cerrejonensis by its discoverers, the size of the snake's vertebrae suggest it weighed 2,500 pounds and measured 42.7 feet nose to tail tip. A report describing the find appears in this week's Nature.

Drs Jason Head and David Polly carried out much of the quantitative work behind the discovery whilst working in the School of Biological and Chemical Sciences at Queen Mary, University of London; they identified the position of the fossil vertebrae which made a size estimate possible. Now based at the University of Indiana, Polly explains: "At its greatest width, the snake would have come up to about your hips. The size is pretty amazing.
