One of the largest dinosaurs that ever lived, Tyrannosaurus rex
was a fierce carnivore. Scientists believe this powerful predator could
eat up to 500 pounds (230 kilograms) of meat in one bite.
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-meter-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
meters) tall. Its strong thighs and long, powerful tail helped it move
quickly, and its massive 5-foot-long (1.5-meter-long) skull could bore
into prey.
T. rex's serrated, conical teeth were most
likely used to pierce and grip flesh, which it then ripped away with its
brawny neck muscles. Its two-fingered forearms could probably seize
prey, but they were too short to reach its mouth.
