Tyrannosaurus Rex was a huge meat-eating dinosaur that lived during the late Cretaceous period, about 85 million to 65 million years ago. They could grow up to 13 metres long, about 5 metres tall and weighed between 5 to 7 tons. The skull of a Tyrannosaurus Rex measured about 1.5 metres long with teeth measuring up to 20 centimetres in length.

Tyrannosaurus Rex were fierce predators that mainly preyed on large plant eating dinosaurs. They had a huge head with large teeth and well-developed jaw muscles. They walked on two powerful legs but had only tiny arms. Their stiff, pointed tail provided balance that allowed for quick turns while running. Although its body was solidly built its bones were hollow.
