Tyrannosaurus (Cretaceous)

Tyrannosaurus is a gigantic extremely popular Late Cretaceous period dinosaur inhabited western North America about 68 million years ago. Tyrannosaurus, whose name means “king of the tyrant lizards”, was one of the most ruthless predators ever walking the Earth.
It is often called T-Rex where “Rex” means a “king”. This is explained by its huge body size. It was 12 metres long and weighed about 9 tonnes. It height to the hip was about four metres. Such a massive body was balanced by stiff and long tail. It moved on two muscular hind limbs. Its forelimbs looked funny being disproportionately small but were ended up with two sharp claws. It should have been caused by mighty and terrible jaws, which T-Rex crunched other dinosaurs with. By the way, scientists cannot exactly determine if the reptile was a predator or scavenger yet.
