Tyrannosaurus

Tyrannosaurus, or rather Tyrannosaurus rex, "tyrant lizard king," is quite possibly the most familiar meat-eating dinosaur that lived about 66 million years ago towards the end of the Cretaceous period. Its fossils exist in what is now North America, primarily the United States and Canada.

Tyrannosaurus had a giant skull with hard jaw and toothed teeth 30 cm (12 inches) long. Tyrannosaurus had one of the most fully developed senses of smell of all dinosaurs, a sense that could be used either as a hunter or scavenger.

The body of a Tyrannosaurus was 12-13 meters (about 40-43 feet) long, about 4 meters (13 feet) tall, and weighed as much as 9 tons. It could, in some estimates, travel at up to 30 km/h (about 18 mph).

Because of its enormous size, foreboding physique, and frequent appearances in films and documentaries, Tyrannosaurus rex is now an archetypal symbol of the prehistoric era. It is also popularly referred to as the "king of dinosaurs."

Facts about Tyrannosaurus: T. rex had just two fingers on its short front limbs, but its hind legs were incredibly strong. Its bite force was over 6 tons, making it one of the most powerful bites on terrestrial animals in Earth's history. Although its arms would have looked comically short, they were actually incredibly strong.

Tyrannosaurus continues to be a paleontologist and dinosaur enthusiast favorite. Its face continues to inspire scientists, filmmakers, and kids around the world.
