Tyrannosaurus rex was one of the largest meat-eating dinosaurs that ever lived. Everything about this ferocious predator, from its thick, heavy skull to its 4-foot-long (1.2-metre-long) jaw, was designed for maximum bone-crushing action.
Fossil evidence shows that Tyrannosaurus was about 40 feet (12 meters) long and about 15 to 20 feet (4.6 to 6 metres) tall. Its strong thighs and long, powerful tail helped it move quickly, and its massive 5-foot-long (1.5-metre-long) skull could bore into prey.
Size: 40 ft (12 m) long; 15 to 20 ft (4.6 to 6 m) tall
Did you know? Tyrannosaurus means "tyrant lizard."
