Millions of  years ago dinosaurs lived in deserts, skies, forests and water. When the dinosaurs died out, they  turned into fossils. Fossils are bones that turn into rock and in the rock you can see the dinosaurs the hard bits like claws and bones. These days, people find the fossils.These people are called paleontologists.Recently in 2015, in China some people found teeth in a cave.They the think that the people belonging to the teeth died thousands of years ago. The teeth were fossils.
