Scientists have reconstructed the world’s largest known snake — a 46-foot prehistoric giant that ruled the Paleocene epoch.

Discovered in 2009 at the Cerrejón coal mine, Titanoboa cerrejonensis remains the largest snake species ever identified. This enormous reptile lived approximately 60 million years ago in the humid rainforests of the Paleocene era. Researchers estimate it reached lengths of up to 46 feet (14 meters), weighed around 2,500 pounds (1,135 kilograms), and measured nearly 3 feet wide at its thickest point.

Its immense size made it an apex predator capable of overpowering large prey, including ancient crocodilians and giant turtles. Unlike venomous snakes, Titanoboa killed by constriction, using extraordinary muscular strength to crush and suffocate its victims.

Modern reconstructions of Titanoboa highlight just how massive the animal was, with a body as thick as a human waist. Beyond its terrifying appearance, the discovery also provided scientists with valuable insight into Earth’s ancient climate. Researchers concluded that tropical regions during the Paleocene were significantly warmer than previously believed, since cold-blooded reptiles of such enormous size could only survive in very warm environments.

The species was formally described in a 2009 study published in Nature by researchers including Jason J. Head and colleagues.
