Last of the Dinosaurs: The Cretaceous Period (The Prehistoric Earth)

This entry in the Prehistoric Earth series discusses how the changing ecological and geological conditions in the Early and Late Cretaceous periods created opportunities for the expansion of dinosaurs. It was also these very climatic and geologic shifts that contributed to the eventual extinction of large and small dinosaurs. Divided into four sections, the book covers such subjects as sauropods, theropod giants, feathered dinosaurs, the origins of birds, iguanodontids, hadrosaurs, and pterosaurs. The final section of the book also examines non-dinosaurian reptiles of the Mesozoic Era. Holmes, a specialist in ­natural-history subjects, is thorough, clear, and informative in explaining theories relating to the mass extinction of dinosaurs and other creatures of the time.
