Aside from Deinosuchus, Albertosaurus does have one other natural rival. The Gorgosaurus.
— Allen, about Gorgosaurus

Gorgosaurus (name meaning "Dreadful Lizard") is a genus of tyrannosaurid theropod dinosaur that originated during the Late Cretaceous period in what is now North America. Though only measuring around 8 meters long and weighing over 2 tons, this vicious predatory dinosaur was a relative of Tyrannosaurus rex and Tarbosaurus.

In the episode "Lake Primal", a pack of several Gorgosaurus, four adults and some offspring, were brought back to the park from Late Cretaceous of 75 million years ago. The leader of the pack is a large male named Gorgo.

FactsEdit

Era & DiscoveryEdit

Gorgosaurus lived in North America during the Late Cretaceous period, from 76–65 million years ago, and died out with all other dinosaurs at the end of the Cretaceous. Though Gorgosaurus was one of the apex predators in its region, it lived alongside other tyrannosaurs, like Albertosaurus, therefore, it is possible that the two species were rivals. It lived alongside dinosaurs and other creatures like Pachyrhinosaurus, Edmontosaurus, Troodon, and Quetzalcoatlus.

Gorgosaurus was first described by Lawrence Lambe in 1914. Gorgosaurus was one of the tyrannosauroids that lived only after the famous Tyrannosaurus rex evolved, and as in the case of Gorgosaurus, they were only a dozen or so feet shorter than Tyrannosaurus rex already in their day, millions of years after the King of the Dinosaurs appeared in North America as the largest and most terrifying tyrannosaurid that ever walked the Earth.

Physical DescriptionEdit

Gorgosaurus was a tyrannosaurid similar in size to other smaller tyrannosaurs, like Albertosaurus. Therefore, it was smaller than larger ones like Tyrannosaurus rex and Tarbosaurus. Gorgosaurus was a fearsome predator that reached an adult size of roughly around 26 feet (8 m) long, stood around 10 feet (3 m) tall, and weighed just over 2.5 tons (5,000 lbs.) in mass. Gorgosaurus' main features are two horn-like bumps on its head above the eyes. Additionally, like all tyrannosaurids, Gorgosaurus possessed small, two-fingered arms.

Like Albertosaurus, Gorgosaurus was a finely balanced carnivore and had large, muscular and powerful legs, being more agile than Tyrannosaurus rex and likely able to reach a top speed of around 30 mph (48 km/h). Therefore, Gorgosaurus was extremely fast, especially for a large animal.

Additionally, Gorgosaurus packed a powerful bite greater than anything alive on land today can match, bearing 60 serrated, sharp teeth in its mouth, made for slicing through flesh and cracking bones. With this, it was able to consume hundreds of pounds of meat in a single bite. Gorgosaurus also had an acute sense of smell as well as hawk-like eyesight.

Behavior & TraitsEdit

Gorgosaurus hunted and traveled in packs of at least four individuals, like all tyrannosaurs and other predators, which allowed it to ambush and pursue its prey. Gorgosaurus hunted large dinosaurs like hadrosaurs, ceratopsians, and ankylosaurs and, like most other animals, may have even been cannibalistic.

When hunting, the pack of Gorgosaurus laid in wait, getting into ambush positions to stay out of sight of their prey. They did this to pick out the weakest members of the herd. Once they had their target selected, they came out of their ambush positions and would chase their prey, causing panic and biting at them as well. With high-tech hunting strategies, they enacted their plan to separate the youngest and weakest members of the herd. This implies that Gorgosaurus was a smart predator.

Additionally, during mating season, the horn-like bumps on Gorgosaurus's head were probably used for display in courtships, as these would be no use in battle, unlike horned ceratopsians. In that case, they would've been brightly colored.
