After the mass extinction of 250 million years ago, one group of reptiles called dinosaurs started to dominate all others. Their name means terrible lizard. They were the commonest vertebrates for the next 150 million years. During their rule there were plant-eating and meat-eating ones, walking, flying and swimming dinosaurs, big ones, small ones.
At the time when the dinosaurs became dominant, all the land of the Earth was gathered together into Pangaea. |
