T-Rex Facts
The Tyrannosaurus rex, commonly called the T-Rex, was a large dinosaur that lived in western North America during the Crustaceous Period, between 68 and 66 million years ago. At the time, western North America was an island continent referred to as Laramidia. The T-Rex was one of the last non-flying dinosaurs to exist before the extinction event. The T-Rex grew as long as 42 feet, as tall as 20 feet, and weighed as much as 9 tons. His skull alone could reach a length of 5 feet. The T-Rex is also known to have had the largest dinosaur tooth of all carnivorous species, with up to 60 serrated teeth reaching 12 inches (including the root). Although impossible to prove, the T-Rex is believed to have been capable of reaching speeds of up to 43 miles per hour.
