As the Ice Age came to an end, North America lost a stunning variety of animals. Mammothmastodons, ground-dwelling sloths the size of elephants, beavers the size of bears, pronghorn antelope the size of poodles, llamas, and carnivores to chase them – sabertooth cats, dire wolves, American lions and cheetahs; these and many more were gone by 10,000 years ago.
Giant Sloths and Sabertooth Cats surveys all these animals, with a particular focus on the Great Basin. Giant Sloths and Sabertooth Cats also explores the major attempts to explain the extinctions. Because some believe that they were due to the activities of human hunters, the author also reviews the archaeological evidence left by the earliest known human occupants of the Great Basin, showing that people were here at the same time and in the same places as many of the extinct animals.
Were these animals abundant in the Great Basin? A detailed analysis of the distinctive assemblages of plants that now live in this region leads to a surprising, and perhaps controversial, conclusion about those abundances.

"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."

"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."
