Scientists discovered the vertebrae of Titanoboa cerrejonensis in northern Columbia in 2009. Scientists believe the snake was the largest vertebrate on land at the time of its existence, with a total weight of over a ton. Scientists measured the bones of its spinal column at 5 inches thick. The Titanoboa?s thickest section was about the height of a human?s waist.
Though Titanoboa's appearance likely resembled a present-day boa constrictor, its behavior was more similar to a water-dwelling anaconda. Scientists believe the swamp denizen killed its prey by squeezing it to death.Learn more about Snakes
