Titanoboa (/tiˌtɑːnoʊˈboʊə/) is an extinct genus of very large snakes that lived in what is now La Guajira in northeastern Colombia. They could grow up to 12.8 m (42 ft) long and reach a weight of 1,135 kg (2,500 lb).[1]

Fossils of Titanoboa have been found in the Cerrejón Formation,[2] and date to around 58 to 60 million years ago. The giant snake lived during the Middle to Late Paleocene epoch,[3] a 10-million-year period immediately following the Cretaceous-Paleogene extinction event.[4]

The only known species is Titanoboa cerrejonensis, the largest snake ever discovered,[3] which supplanted the previous record holder, Gigantophis. - Wikipedia
