Dinosaurs lived on the earth for 135 million years. They appeared 200 million years ago, and they disappeared 65 million years ago. They were the largest animals ever to live on earth, and they ruled the earth for a very long period of time. Dinosaurs lived in North America, in Africa, and in Europe. During that time, the land in North America was under a large, shallow sea.
Why did dinosaurs die out? Nobody knows for sure. Probably a change in the climate made serious problems for them. About 70 million years ago, the Rocky Mountains formed in North America. The plant life and the weather changed. Perhaps the dinosaurs couldn`t change fast enough. People who like dinosaurs can see fossils in Dinosaurs National Park. This park is in Utah and Colorado. Fossils are bones which have become stones. Fossils have taught us a lot about these great animals of the past.
