"Who discovers dinosaurs? What happens to a dinosaur bone when it's found? What exactly were dinosaurs, anyway, and how many different kinds were there? In this simple-but-thorough book, Gail Gibbons covers the basics of paleontology, dinosaurs, dinosaur families and evolutions, and the K-T extinction. This new and updated edition features the latest information on dinosaurs and how scientists study them"--
