This document provides an overview of dinosaurs. It explains that dinosaurs lived over 215 million years ago and ruled Earth for around 150 million years before going extinct 65 million years ago. Paleontologists study dinosaur fossils to learn about dinosaurs. Fossils are formed over millions of years as animal bodies become buried in sediment that later turns to rock. Studying fossils has shown that dinosaurs came in various sizes and had different diets, locomotion styles, and habitats. Some walked on four legs while others had two legs, wings, or swam. Famous dinosaurs mentioned include Stegosaurus and Tyrannosaurus Rex.
