The Giganotosaurus was a large carnivorous dinosaur that lived during the Late Cretaceous period. It was one of the largest known predatory dinosaurs, possibly reaching lengths of up to 47-49 feet. Giganotosaurus had large, sharp teeth and powerful jaws that it used to hunt other dinosaurs. It was bipedal, meaning it walked on two legs and had a long tail that it likely used for balance.
Giganotosaurus was a theropod dinosaur, which is a group that includes other large carnivorous dinosaurs such as T. rex and Allosaurus. Fossils of Giganotosaurus have been found in Argentina, indicating it lived in South America.
