One of my favourite dinosaurs is T-Rex! Let’s discover five terrific T-Rex facts for kids.

T-Rex Facts for Kids Fact Number 1: The Name Tyrannosaurus Rex Means ‘Tyrant Lizard King’

The word originated from the Greek and Latin language. ‘Tyrannosaurus’ comes from the Greek words meaning ‘tyrant lizard’, while the word ‘rex’ means ‘king’ in Latin. The Tyrannosaurus rex, or T-Rex for short, is probably the most recognisable dinosaur of them all.

T-Rex Facts for Kids Fact Number 2: The T-Rex Was a Carnivore

The Tyrannosaurus Rex was a carnivore. This meant it only ate meat. The T-Rex had a set of 50 big and sharp teeth in its mouth, this allowed it to eat meat much easier and quicker. The T-Rex has the largest tooth of any carnivorous dinosaur found to this date and that of a T-Rex. The T-Rex tooth is estimated to have been around 30cm long, the length of a ruler. It had the strongest bite of any land animal to ever exist and with one bite, it could rip off a hundred pounds of meat!

T-Rex Facts for Kids Fact Number 3: The T-Rex Was Really Tall

 The T-Rex lived during the late Cretaceous Period, which was roughly 65 million years ago. Most fossils have been found in the USA and Canada. The T. Rex was a very tall beast which reached heights of up to 6 metres and 12 metres in length.

Scientists believe the Tyrannosaurus rex could run at speeds of up to 20 kilometres per hour. It is safe to say we humans could not outrun a T-Rex. One  of the T-Rex’s most notable features is its two tiny clawed arms, which were less than one metre in length. It is believed that the shortness of their hands was because it would take less energy to support such small arms and the likeliness of breaking them was less.

T-Rex Facts for Kids Fact Number 4: The T-Rex Was very Intelligent

The T-rex was super smart, it had a brain twice as big as those of the other giant dinosaurs. The skull of a Tyrannosaurus rex measured up to 1.5 metres in length. This made room for the T-Rex’s huge brain. The size of the T-Rex’s brain suggests that it might have been more intelligent than other dinosaurs. It also gave the T-Rex stronger senses including great eyesight, hearing and smell. This was a great advantage when hunting prey.
