The Beautiful Dinosaurs
Dinosaurs are the most mysterious reptiles that have ever lived on the Earth. Some dinosaurs were the size like a chicken; the others – like a modern plane. There were cunning hunters and blood-thirsty predators among them. But there were also harmless animals.
The most dinosaurs lived on the land but some groups learned to live in the sea. Flying reptiles were contemporaries with dinosaurs.
The period of Dinosaurs had been lasting on the Earth almost 150 million years. After many centuries dinosaurs have become heroes of the myths and legends. Having found the remains of dinosaurs, people have made many fantastic stories about the creatures that had so huge bones.
Dinosaurs became extinct 65 million years ago. Nobody knows what the cause was. Scientists think it happened after the fall of a huge meteorite or after a volcanic eruption.
