Over 500 photos and engaging text reveal the fossils of the Cretaceous Period, the last period of the Mesozoic Era, the "Age of Reptiles," dating from 120 to 67 million years ago. Included are typical Mesozoic fossils, such as the ammonites, belemnites, and other collectible fossil mollusks characteristic of the Cretaceous, a variety of plants, well-preserved arthropods such as crabs and insects, turtles, crocodiles, and dinosaurs. Fossils recovered range from the Early Cretaceous to the Upper Cretaceous III, ending at the KT boundary representing the events that swept dinosaurs off the face of the planet. Each fossil displayed is carefully identified, along with the region from which it was recovered. The book aids fossil collectors and all who are intrigued about the fascinating artifacts of this early age.
