Tyrannosaurus Rex

The name of Tyrannosaurus Rex comprises of the Latin words “Tyrant Lizard King”. The species is commonly known as T-Rex. If you have seen Jurrassic Park or Jurassic World, then you may have observed the T-Rex and its speculated behaviour.

T-Rex was one of the largest carnivores to ever walk the face of the Earth. The predator had a thick and heavy skull, and powerful jaws. Its jaws were designed to tear through flesh and crush bones. The conical teeth were built for piercing and tearing flesh from its prey’s bones.

Size & Physique

Tyrannosaurus grew to as large as 12 metres long, and 6 metres tall. Given its large size, many have mistakenly believed it to be a slow, sluggish scavenger. However, this beast had strong thighs and a long tail, which aided its balance while in pursuit.


This dinosaur was a meat eater, and likely hunted medium-large herbivores, such as Triceratops, Edmontosaurus and Anatosaurus.

Discovery & Location

T-Rex was discovered in western North America. It lived in the late Cretaceous period, and became extinct 66 million years ago.
