Encyclopedia of Prehistory

Encyclopedia of Prehistory is a comprehensive, up-to-date key to the processes that forged our planet and the vast array of prehistoric animals, plants, and other organisms that appeared on, and vanished from its surface. Featuring more than 1,500 illustrations and diagrams, the encyclopedia is arranged in chronological order so that explanations of Earth's formation and its features may precede accounts of its major categories of life-forms.
