Titanoboa was the largest snake ever known, living around 60 million years ago during the Paleocene epoch in what is now Colombia. It reached lengths of up to 12–15 meters (40–50 ft) and weighed more than 1 metric ton, making it far larger than any modern snake. Unlike today’s giant constrictors, Titanoboa thrived in the hot, humid tropical climate of ancient South America.

It was a powerful constrictor, likely preying on large fish, crocodile-like reptiles, and even turtles in the swampy ecosystems of the Cerrejón Formation. Fossil evidence, including vertebrae and skull fragments, suggests Titanoboa spent much of its life in the water, similar to modern anacondas.

Its discovery not only revealed the existence of the largest snake in Earth’s history but also gave scientists insight into ancient climates, since such a massive reptile could only survive in extremely warm tropical conditions. Titanoboa remains one of the most iconic examples of prehistoric megafauna
