The Petrified Forest of Arizona seemed like the perfect place to start to search for fossils, writes our hero in his 1929 journal. Thus begins the exciting hunt for dinosaurs and their prehistoric secrets in "The Field Guide to Dinosaurs." Through a series of journal entries, readers uncover the mysteries of the dinosaur kingdom from the speedy and agile Coelophysis to the existence of Pangaea, the landmass of some 227 million years ago when all of the continents were one. Junior paleontologists can experience the excitement of a dig as they rifle through maps, illustrations, and engaging interactive elements, including seven dinosaur models and a museum-ready diorama that they can easily assemble themselves."
