Gorgosaurus was a large theropod dinosaur that lived during the Late Cretaceous period, around 76 to 75 million years ago. It was primarily found in what is now North America. Gorgosaurus was a carnivore, known for its sharp teeth and strong legs, which made it an effective predator. This dinosaur could grow up to 30 feet long and weighed around 2.5 tons. Its skull featured large, forward-facing eyes, suggesting it had good vision. Gorgosaurus is closely related to Albertosaurus and Tyrannosaurus rex, sharing similar physical traits and hunting strategies.
