Giganotosaurus was one of the largest carnivorous dinosaurs, slightly larger than Tyrannosaurus, but a little shorter than the Carcharodontosaurus (although weighed more than the latter) and nificantly smaller than the Spinosaurus. It grew up to 13.5 meters (44.2 feet) in length, but new fragmentary remains indicate that it could grow even more.

Had a skull along 1.65 m, longer than that of Tyrannosaurus, and equipped with long teeth up to 20 centimeters. His brain, however, was the size of a banana, and it was 275 cubic meters smaller than Tyrannosaurus, but 18% bigger than that of his kinsman Carcharodontosaurus.
