The largest crocodilian in history and was well known for killing and eating the single largest prey during it's time.
The sarcosuchus is a 40 foot long behemoth and was an ambush predator. It would often target the young of it's prey with little to no effort. Fossil however did find Giganotosaurus bones near it's stomach so it's not out of the realm of science to believe it killed it for food.
During the start of the episode it tried to attack Nigel both times failing.
- This crocodilian and Deinosuchus while related are actually from different gene's. Deinosuchus is an Alligator while Sarcosuchus is a crocodile.
