8 tonnes of pure muscle. 60 razor-sharp serrated teeth. A bite force that could cut through bone like you do a powdered doughnut. Quite simply the most formidable predator the Earth has ever known.
Tyrannosaurus rex, which means "Tyrant Lizard King", was a huge meat-eating dinosaur found in western North America in rocks from the end of the Cretaceous period, about 68 million to 65 million years old. T. rex walked on its two hind legs, while the function of its tiny but powerful arms remains uncertain.
Tyrannosaurus rex was among the largest known of the meat-eaters. Its eyes faced forward, giving it stereoscopic vision. The structure of its jaw allowed all the teeth to engage at once when biting. To support its massive head, its body and neck were short and deep compared with other carnivorous dinosaurs. The tail was long to balance the body and head. Many of its massive bones were hollow, which reduced the weight of the skeleton while still providing strength.
T. rex was among the last dinosaurs to exist prior to the Cretaceous-Tertiary (K/T) extinction event. |
