Gorgosaurus libratus

Gorgosaurus libratus was a sleek, bipedal tyrannosaurid that prowled the lush coastal plains of ancient western North America. Equipped with long lower leg bones and dozens of blade-like, serrated teeth, it possessed exceptional agility compared to bulkier apex carnivores of its era. Remarkable fossil discoveries indicate that juveniles focused on chasing small, agile bird-like dinosaurs before transitioning into heavy-jawed hunters of adult hadrosaurs and horned ceratopsians.
