Publisher's Synopsis
Dinosaurs: The Essential Guide to This Amazing Animal with Amazing PhotosDinosaurs are animals that existed more than 200 million years ago. Dinosaurs are all extinct, which means that none of them are living today. If so, how was it possible to know that they really existed on Earth before?There are people who study fossils-the remains of life in the past-and they are called paleontologists. These people found lots of fossils of dinosaurs. Most of the fossils they found were the bones of many types of dinosaurs. Dinosaurs come in many types. Some were carnivorous or meat eaters, others were herbivorous or plant eaters. Though everyone knows about them, nobody has seen them in person.
