The (Cerrejón) river basin held turtles with shells twice the size of manhole covers and crocodile kin—at least three different species—more than a dozen feet long. And there were seven-foot-long lungfish, two to three times the size of their modern Amazon cousins."How Titanoboa, the 40-Foot-Long Snake, Was Found"
The lord of this jungle was a truly spectacular creature—a snake more than 40 feet long and weighing more than a ton. This giant serpent looked something like a modern-day boa constrictor, but behaved more like today’s water-dwelling anaconda. It was a swamp denizen and a fearsome predator, able to eat any animal that caught its eye. The thickest part of its body would be nearly as high as a man’s waist. Scientists call it Titanoboa cerrejonensis.
It was the largest snake ever, and if its astounding size alone wasn’t enough to dazzle the most sunburned fossil hunter, the fact of its existence may have implications for understanding the history of life on earth and possibly even for anticipating the future.
