Titanoboa cerrejonensis
One of the largest snakes to have existed, certainly the heaviest with a length of ~45ft(~14m) and weights reaching a ton. Titanoboa lived during the Paleocene in South America with other very large reptiles.
Analysis of skull material reveal a piscivorous diet. Many large lungfish & bony fish called the Cerrejón water systems home which proved a boon to the massive serpent.
