- 英文:Dinosaurs lived on Earth more than 60 million years before human beings. They lived in every corner of the Earth. Some dinosaurs were as small as chickens. Others were as big as ten elephants. Some could even fly. Many dinosaurs ate plants. But there were also some dinosaurs that liked to eat meat. Dinosaurs lived on Earth for more than 150 million years.
