This book is primarily about dinosaurs, but also delves into paleontology, geology, climatology, and the history of the Earth itself! It isn't about those run-of-the-mill normal dinosaurs, however; you'll find only decidedly Weird ones in here, like the dinosaur with four wings! The book is aimed at kids who are beyond picture books and are interested in real science (although not necessarily destined to be scientists). Do you know any curious kids who enjoy "out smarting" their elders by spouting facts about prehistoric varmints?
