Giganotosaurus (meaning "giant southern lizard") is a genus of theropod that lived in Argentina during the Late Cretaceous period. It is currently one of the largest known meat-eating dinosaurs and the largest carnosaur to ever exist. For many years Tyrannosaurus held that record, although bits and pieces of Carcharodontosaurus and Spinosaurus showed that they possibly could rival the giant coelurosaur in size. Then, in the late 1980s into the early 1990s, Argentine paleontologists Rodolfo Coria and Leonardo Salgado discovered and revealed the existence of a new meat-eater bigger than any known tyrant lizard. They named the giant dinosaur, Giganotosaurus carolini.

While determining exactly which theropod genera was the largest, metrics for Giganotosaurus have consistently placed it as larger than an average Tyrannosaurus rex and comparable to the largest known specimens of the Tyrant Reptile King. More specimens of the Giant Southern Reptile are required to give a clearer picture of size, as all species will exist within a spectrum of sizes. For now it is safest to consider the likes of Giganotosaurus, Spinosaurus, and Tyrannosaurus as comparable to one another in terms of size.

When Giganotosaurus was alive, the most common herbivores found in South America were the titanosaur sauropods. While a single Giganotosaurus was capable of killing a young titanosaur or a large ornithopod, it would take many Giganotosaurus' to bring down a giant adult sauropod. Originally, there was no evidence that Giganotosaurus hunted in groups, but recent findings from slightly younger rocks shows that they may have formed coalitions similar to crocodiles. While not true pack living behavior, these coalitions of 6 or more individuals would be capable of coordinating on targets of opportunity such as a large sauropod.


Genetic material of Giganotosaurus was in possession of InGen by the year 2014 and was used in the creation of the genetic hybrid Indominus rex.[1]

Jurassic World: Dominion

In the Past

In a flashback to the Cretaceous period, a Moros scavenged morsels of meat stuck between the teeth Giganotosaurus, before the larger predator sensed something approaching and rose. A nearby Iguanodon looks up at the Giganotosaurus, but is ignored as its attention is instead focused on the arrival of a feathery Tyrannosaurus rex. The Tyrannosaurus circled and roared a challenge to the carnosaur, whom refused to back down and met the challenge. The Tyrannosaurus attempted to lunge at its rival's throat, but the Giganotosaurus deflected the hit by bashing its skull into the feathered tyrant reptile and stunned it just long enough to seize the Tyrannosaurus by the throat. The two turned and thrashed about, with the Giganotosaurus nearly slipping off a sheer drop into a sink hole behind it, before regaining it's footing and grip on its rival. Turning about, the Tyrannosaurus was killed; likely by a combination of the Giganotosaurus' teeth garroting its throat and the sudden drop into the sinkhole breaking its neck. After the battle, it leaves its enemy's body behind and walks off. A mosquito lands on and bites the deceased Tyrannosaurus rex, giving the scientists of Jurassic Park the chance to create Rexy, the modern descendant of the very same T. rex which died in the jaws of the Giganotosaurus.

  • An artistic render of Giganotosaurus, created by the Natural History Museum, is seen on a wall of one of the stores inside Jurassic World's Main Street.
  • Despite being grouped with abelisaurs (Carnotaurus, Majungasaurus, and Rugops) and being called an abelisaur on the website, it is actually classified as a Carcharadontosaurid.
  • In real life, Giganotosaurus could have never fought Tyrannosaurus rex, as the latter lived in North America while the former lived in South America and 30 million years before T. rex, and the two continents were not connected by a land bridge until 15-12 million years ago.

Behind the scenes

  • Giganotosaurus was once rumored to be the dinosaur antagonist of Jurassic World, then called by its preliminary name "Jurassic Park IV", before Indominus rex was revealed to be the antagonist. However, it did appear in the film in a sense as its genetic material was used in Indominus rex's creation.[1]
  • Giganotosaurus was featured in some concept art for Jurassic World: Fallen Kingdom. However, Colin Trevorrow confirmed there were no plans for it to be added to the final cut.
  • The design of this Giganotosaurus has many features that differentiate it from its real-world counterpart. Some of these were specifically added to make it look dissimilar to the Tyrannosaurus [2]
    • A hump on it's back, half way down its spine, as well as the addition of spikes.
    • A thick tail, which could be the result of a larger body.
    • Giganotosaurus is the larger and taller predator, similar to the Indominus and Spinosaurus.
