Sucuriju Gigante (Giant Anaconda), is said to be giant snake that controls the rivers it lives in. There are ancient tales that say it made the Amazon River. Since the discovery of the fossils of Gigantophis garstini, a large snake from the Priabonian age of the Eocene ( about 30 million years ago) that could reach 33 feet (11 metres) in length, and the more recently discovered fossils of Titanoboa cerrejonensis( from about 50-60 million years ago) that reached 43 feet (14 metres), there has been some speculation it could actually exist and be an ancestor of the prehistoric creature. There have been supposed sightings of giant snakes in South America for many years . In 1846, George Gardner wrote about his travels in Brazil. He said he saw a dead giant snake on the lands of a Senor Lagoeir
