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 40 to 50 feet long (12–15 m), and weighed over a ton. The snake lived in the Palaeocene epoch, about 58 million years ago. It was about three feet (1m) in diameter at the thickest part of its body.
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.
