Published in association with America's preeminent authority, the Smithsonian Institution Authoritative text, crystal-clear artwork, and a systematic approach make DK's Smithsonian Handbook of Dinosaurs and Prehistoric Life the most comprehensive pocket guide to these early creatures and the world they inhabited millions of years ago. Encyclopedic Approach For ease of reference, the main body of the book is divided into three sections: the Precambrian and Palaeozoic eras, the Mesozoic era, and the Cenozoic era. Each section is broken down into its geological time periods, and, within these, the species are organized according to habitat-whether they lived on land, in the water, or in the air. In-Depth Information There are detailed profiles of 200 dinosaurs and other ancestors of modern animals. Each entry combines a precise, jargon-free description with full-color artworks, skeletons, and replica models, annotated to pinpoint the key features of the species. Maps show where the animal's fossils have been found, and many profiles are supported by photographs to show actual excavation sites.Richardson, Hazel is the author of 'Dinosaurs and Prehistoric Life Dinosaurs and Prehistoric Life', published 2003 under ISBN 9780789493613 and ISBN 0789493616.
