The word ‘Dinosaurs’ comes from two Greek words: ‘deinos’, which means ‘terrible’, and ‘sauros’, which means ‘lizard’. Therefore ‘dinosaur’ means ‘terrible lizard’.

Some dinosaurs were carnivores, meat-eaters, and some were herbivores, plant eaters.

Some walked on two legs, while others walked on all four legs. Some had horns and spikes, others had thick bumpy skin, and some even had feathers.

Scientists who study dinosaurs are known as Palaeontologists. 

Fun Facts

Tyrannosaurus rex (also known as the T-Rex) looked the most ferocious of all the dinosaurs.  It is believed that a T-rex bite was more than twice as powerful as a lion’s bite. 

The longest and the heaviest dinosaur was Argentinosaurus, which measured over 40 metres.

One of the most intelligent dinosaurs was Troodon. It was a hunting dinosaur, about 2 metres long.

Stegosaurus had a brain the size of a walnut – only 3 centimetres long and weighing 75 grams. These were probably one of the dumbest dinosaurs.

The speediest dinosaurs were the Dromiceiomimus. They looked like ostriches and could probably run at speeds of up to 60 kilometres per hour.
