Description

Long before humans appeared, reptiles called dinosaurs roamed and ruled the Earth. Theirs was a very different world from ours, and many different types of dinosaurs learned to live among the thick forests and on the vast plains.

Small and speedy hunters chased after the prey. Giant plant eaters gobbled the leaves and flowers. Some of these reptiles took to the water, and some learned to fly. Then, suddenly and mysteriously, they all disappeared.
