Over 20 Gorgosaurus skeletons have been recovered, making it the most well-represented tyrannosaurid in the fossil record. Generally similar to Tyrannosaurus and most other large tyrannosaurids (such as Daspletosaurus, and Albertosaurus), Gorgosaurus can be described as having a massive head, large, curved teeth, tiny two-fingered front limbs, and powerful legs. Compared to the other tyrannosaurids, Gorgosaurus is most similar to its very close relative Albertosaurus.
Although it has been suggested that Gorgosaurus was a scavenger, its co-existence with the similarly sized, but more robust tyrannosaurid Daspletosaurus casts doubt on this theory. Another hypothesis proposes that Gorgosaurus, which was rather lean for a tyrannosaurid, actively hunted fleet-footed animals such as duckbills and ornithomimids ("ostrich-mimic" dinosaurs). According to this proposition, the more troublesome ceratopsians and ankylosaurians (horned and heavily armoured dinosaurs) would have been left to Daspletosaurus. An apex predator, it was at the top of the food chain.
For years, the species Gorgosaurus libratus (the only species of Gorgosaurus currently recognized) was assigned to the Albertosaurus genus. However, recent work done by paleontologists suggest that enough differences exist between G. libratus and the other Albertosaurus species, to justify the original genus name of Gorgosaurus.
In Popular Culture
Gorgosaurus had a large role in the movie March of the Dinosaurs, where it was show to be "king of the dinosaurs". It also had a large role in Walking With Dinosaurs: The 3D Movie, where it is seen as the main antagonist.
Gorgosaurus appeared in Fossil Fighters, Fossil Fighter Champions, and Fossil Fighters Frontier, as a Fire element revivable dinosaur.
It also appears in Jurassic World: The Game as a tournament dinosaur.
