Graveyard of the Giant Beasts

Discovery of the giant snake, Titanoboa

Experts examined the bones they discovered at the Cerrejón mine. They recognized that although it was the size of a crocodile vertebrae, it actually belonged to a snake. Anacondas are the largest snakes alive today, but their vertebrae are dwarfed when placed next to that of the Cerrejón monster. Weighing more than a ton, this giant snake was five times bigger than the largest alive today.
