“A remarkable and personal account. Grayson brings to life this enthralling menagerie of strange beasts—their relationships, distributions, habits, and chronology—while highlighting the fascinating history of how we have learned about them. Hugely informative and entertaining, a pleasure to read and think about.” —David E. Rhode, research professor of archaeology, Desert Research Institute, Reno, Nevada ""This is an excellent and easily read account of the Ice Age fauna of the Great Basin. It is one of the best at relating the large animals to the vegetation and physical environment of that time and the changes that followed the climate change at the end of the Ice Age. Its discussion of the extinction event, its timing and possible causes, should be read by all scientists working in that area.” —Ernest Lundelius, Jr., Professor Emeritus of Vertebrate Paleontology, University of Texas at Austin
