Tyrannosaurus Rex

Best Dinosaur In The World?

What is Tyrannosaurus Rex?

Best known of the dinosaurs, Tyrannosaurus rex was one of the most awesome creatures that have walked on the earth. T-rex was one of the largest meat - eating dinosaurs, having a skull up to 5ft long and many sharp teeth reaching lengths of 6in (15cm). The first complete Tyrannosaurus rex T-rex skeleton was discovered in 1902, and many great examples have been unearthed over the last fifteen years. A T-Rex is a vertebrate.

Where does it live?

Tyrannosaurus rex lived in forested river valleys in North America during the late Cretaceous period. It became extinct about 65 million years ago in the Cretaceous-Tertiary mass extinction.

What does a T-Rex look like?

Fossil evidence shows thatTyrannosaurus 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.Scientists believe this powerful predator could eat up to 500 pounds (230 kilograms) of meat in one bite. Fossils of T. rex prey, including Triceratops andEdmontosaurus, suggest T. rex crushed and broke bones as it ate, and broken bones have been found in its dung.
