Here are pictures and descriptions of fifty-ton Brachiosaurus, the heaviest of all dinosaurs; huge, peach-loving Brontosaurus; long-necked Diplodocus; fearsome Gorgosaurus; armed dinosaurs such as Stegosaurus; and many others. You will learn how scientists dig the remains of dinosaurs out of rocks, and assemble them in museums so that we may see them today. A time line running through the book helps show how very long ago these creatures lived. With color pictures on every page.
