Millions and millions of years ago,the world was much warmer than it is now.There was never winter or snow.Warm rain fell on the land.Even the sea was warm.In this warm world lived strange animals called dinosaurs.They were the kings of the world for a long time.
In the days of the dinosaurs,there were not men.So no man has ever seen a living dinosaur,But we found their bones and after years of study ,a lot about the dinosaurs have been learned.
Some dinosaurs lived near the water while some lived on dry land.Some ate only plants and some ate other animals.
Many dinosaurs were very large,but some of them were as small as chickens.
