دانلود کتاب Dinosaurs of Darkness: In Search of the Lost Polar World

Dinosaurs of Darkness opens a doorway to a fascinating former world, between 100 million and 120 million years ago, when Australia was far south of its present location and joined to Antarctica. Dinosaurs lived in this polar region.How were the polar dinosaurs discovered? What do we now know about them? Thomas H. Rich and Patricia Vickers-Rich, who have played crucial roles in their discovery, describe how they and others collected the fossils indispensable to our knowledge of this realm and how painstaking laboratory work and analyses continue to unlock the secrets of the polar dinosaurs. This scientific adventure makes for a fascinating story: it begins with one destination in mind and ends at another, arrived at by a most roundabout route, down byways and back from dead ends. Dinosaurs of Darkness is a personal, absorbing account of the way scientific research is actually conducted and how hard and rewarding it is to mine the knowledge of this remarkable life of the past.The award-winning first edition has been thoroughly updated with the latest discoveries and interpretations, along with over 100 new photographs and charts, many in color.
