Carnivorous Dinosaurs

Bio

Giganotosaurus is the second largest predator living on Isla Tronar, dwarfed only by Spinosaurus. It is slightly larger than Tyrannosaurus rex, and its strength and ferocity rivals that of the Tyrant King. Giganotosaurus's hunting style and behavior is different than that of T-rex. Unlike T-rex (which are generally solitary animals), Giganotosaurs live in groups of up to seven individuals. There is little to no social structure in Giganotosaurus pack, and the pack is dominated by the largest and oldest individuals. Giganotosaurus is also one of the only two predators on Tronar that specializes in hunting giant sauropods (the other two being its close relative Carcharodontosaurus), and is most infamous for hunting Argentinosaurus, the largest dinosaur in Jurassic National Park, and one of the largest land animals that ever existed. When hunting Argentinosaurus, packs of Giganotosaurs will target the slowest, sickest, or weakest members of the herd. They will first seperate the animal from the rest of the herd by dashing in and scaring off the other members of the herd, thus exposing the target. The Giganotosaurs will then proceed to kill the argentinosaur, using their blade-like teeth slice off ribbons of meat from the animal. The bloodloss would make the sauropod weaker, and easier to kill.

Age: Early to Middle Cretaceous, 112-93 million years ago

Fossil Finds: Africa (Egypt, Morocco)

Length: 16-18 meters (52-60 feet) long
