About the Dinosaurs 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. Dinousaurs lived in North America, in Africa, and in Europe.During this time the land in North America was under a large, shallow sea. Many dinosaurs lived in the water, which helped to hold up their great weight. The early dinousaurs walked on two feet, and they ate meat. The later dinosaurs were larger and walked on four feet. Some of the later dinosaurs ate plants only. Why did dinosaurs die out? Nobody knows for sure. Probably a change in the weather 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 Dinosaur National Park. This park is in Utah and Colorado. Fossils are bones which have become stone. Fossils have taught us a lot about these great animals of the past.Task 1. Find out the synonyms Task 2. Find out the antonymsTask 3. Find out the names of the places​
