Temporal range: Palaeocene
Titanoboa was the largest known snake. Now extinct, the snake was a relative of the Anaconda and the Boa constrictor. It was about 42 feet long (12.8 m), and weighed over a ton (about 1135 kg or 2500 pounds). The snake lived in the Palaeocene epoch, about 58 million years ago.
The fossil was found in an open-cast coal mine in Colombia, in 2009. Plant fossils at the site proved the climate at the time was a tropical rainforest. The site was in the Cerrejón Formation in La Guajira, Colombia. Other large reptile fossils have been found at this site.
