At around 12m long, the tyrannosaurus rex was one of the biggest carnivores that ever walked the earth. With serrated teeth and a 4ft long jaw, this ferocious predator could eat up to 500 pounds of meat in one bite! According to a 2012 study, the dinosaur’s bite could exert up to 12,814 pounds-force, the equivalent of a medium-size elephant sitting down. Its strong thighs and powerful tail meant it could move quickly, chasing down any potential prey with running speeds of up to 25mph.
Fossils of this predator were discovered in western North America, from Alberta to Texas, where it’s thought to have existed 65 million years ago during the Late Cretaceous Period. The tyrannosaurus rex mainly fed off other plant-eating dinosaurs, with experts believing it either scavenged on carcasses or hunted down its own prey.
