Titanoboa

Titanoboa is an extinct genus of giant snake that lived from the late Cretaceous to the end of the Palaeocene, or from 66-47.8 MYA. A single species from Columbia, Titanoboa Cerrejonensis, has been described. Some estimates put Titanoboa at 50-56 feet, although it is possible that Titanoboa did occasionally suffer from gigantism, which would make it far longer than these estimates. Estimates for weight put it at 3000 pounds, although a large Titanoboa probably exceeded 4000 LBS. On land, its weight would've slowly suffocated it. It lived mainly in the water, where it would feast on fish and crocodilians such as Cerrejonisuchus. Titanoboa supplemented the previous two record holders, specifically the 1000 pound Gigantophis Garstini from Egypt and the 34,000 pound Palaeophis Colossaeus from a large part of Africa. It is also bigger than Vasuki, a large snake that is believed by some to have grown to 50 feet in length.
