Scientists in Colombia have unearthed the remains of a true prehistoric monster believed to be the biggest snake ever to have lived on Earth. Named Titanoboa cerrejonensis, the snake would have weighed 1,140 kilograms (2,500 pounds) and measured 13 meters (42.7 feet) nose to tail tip — dwarfing the largest modern pythons and anacondas which can grow to 6 meters (19.5 feet).
