Dinosaurs! When The Dinosaurs Lived A long, long, long time ago, millions of years ago, before there were any people, Dinosaurs roamed the earth. In those prehistoric days, the earth did not look the way it does today. There were no buildings or roads anywhere. There were rocks, trees, oceans, and rain forests. The dinosaurs roamed the earth and lived just about everywhere. The climate was different too. Imagine how the air feels on a hot summer day. That is what the climate was like during much of the time that dinosaurs lived. Click Here For A More Detailed Description Of Early Dinosaur Times .
