“Up to a point, there are evolutionary advantages to size, and this Giganotosaurus pushes the limits. You're gonna have your hands full with this one.”

Giganotosaurus is a large genus of theropod dinosaur that originated from Late Cretaceous South America. A powerful carnivore, Giganotosaurus is unlocked by the Hammond Foundation for island operations in the Five Deaths upon completion of the Security Division's mission on Isla Pena.
While InGen was not known to have cloned Giganotosaurus for either Jurassic Park or Jurassic World, by 2012, the company had possession of the carnivore's genetic material. This was later used, along with the DNA of numerous other species, to create the genetically modified superpredator known as the Indominus rex, which was responsible for the destruction of Jurassic World in 2015.
Giganotosaurus is more tolerant of others of its own kind, and in contrast to Tyrannosaurus, will happily live in pairs. Like other giant carnivores, its a powerful animal and needs strong fences to contain it.
Giganotosaurus was originally discovered in 1993 by an amateur paleontologist, Reuben Carolini. The discovery was officially recorded by paleontologist Rodolfo Coria in 1995. A team led by Coria and funded by American Paleontologist Don Lessem uncovered roughly seventy percent of the animal. It was soon declared the largest theropod ever discovered, rivalling Tyrannosaurus in size, though other, larger theropods would soon be discovered or re-examined in the following years.
Giganotosaurus is a member of the Carcharodontosauridae family, which evolved in the Late Jurassic and are related to genus such as Allosaurus. The family's earliest genus, Veterupistisaurus, evolved in Late Jurassic Tanzania and in the Early to Mid Cretaceous Carcharodontosaurids could be found in Africa, Asia, Europe, Asia and both North and South America. However, during the Late Cretaceous, they started dying out in Laurasia (the name for the ancient Northern Hemisphere), with the last Laurasian species, Shaochilong, being found in modern China. However, they thrived in the southern continents of Gondwana for a time, though little evidence of them is known by the Campanian stage of the Cretaceous, roughly 85 million years before present day. Other interesting species include the equally giant Carcharodontosaurus from northern Africa, the high-spine Acrocanthosaurus from America, and the humpbacked smaller Concavenator from Spain.
Giganotosaurus lived alongside many species of titanosaur, including some of the largest dinosaurs ever discovered such as Andesaurus, medium-sized sauropods like Limaysaurus as well as numerous smaller dinosaur species. In packs they could possibly have taken down larger sauropods. The bite of Giganotosaurus was weaker than Tyrannosaurus and instead, it would have relied on its sharp, serrated teeth to inflict deep, bleeding wounds to weaken prey instead of utilizing brute strength. This is common in many carnosaurs, such as Allosaurus. It also differentiates them from the Coelurosaurian Tyrannosaurs.
- The skull of Giganotosaurus carolinii is 1.95-1.55 meters in length, longer than that of Tyrannosaurus rex.
- Based on recent evidence, Giganotosaurus was possibly a pack hunter, and is frequently portrayed as such in popular media. It is hypothesised that Carcharodontosaurs like Giganotosaurus were able to to hunt giant sauropods. However, in Jurassic World Evolution, they are unable to do so.
