    Published in association with the esteemed Smithsonian Institution, DK's Smithsonian Handbook of Dinosaurs and Prehistoric Life features authoritative text, crystal-clear artwork, and a systematic approach to its subject matter.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.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.The guide is authored by Hazel Richardson, a former research scientist, lecturer, and teacher. She has written 15 science books, many of which have been published worldwide, as well as educational CDs and scientific articles.

    Stretching from the cypress swamps of Okefenokee to the remote wilderness of Alaska's Arctic National Wildlife Refuge, the refuges now occupy an amazing 95 million acres of the American landscape. These are America's most treasured natural habitats - filled with waterfowl, fish, mammals, and a diverse array of plants." Coupling his text with the remarkable photographs of John and Karen Hollingsworth, Eric Dolin draws on the rich history surrounding the refuges to reveal an intriguing story of people and nature. After exploring how the fledgling conservation movement found its champion in Teddy Roosevelt, Dolin unveils a story filled with heroic, sometimes quirky, Americans who fought to preserve the nation's natural heritage. Following Roosevelt's lead - and against a backdrop of the twentieth century's wars and strife - refuge after refuge was created, resulting today in an incredibly diverse and biologically critical system that helped earn the United States its reputation as a leader in global conservation."Outstanding book . . . Highly and enthusiastically recommended for all public libraries and all environmental collections." Library Journal"A terrific job . . . The result is a coffee table book worth buying a coffee table for." The Baltimore Sun"The remarkable photographs and accompanying text reveal the rich history of America's 538 national wildlife refuges." Outdoor Photographer"The stories of Teddy Roosevelt . . .
