The Extinct Ice Age Mammals of North America

University of Washington Anthropology Professor Donald Grayson and recipient of the 2015 University Faculty Lecture Award delivers the University Faculty Lecture on April 28, 2016. Toward the end of the Ice Age, North America saw the extinction of an astonishing variety of often huge animals. Mammoths, mastodons, saber-toothed cats, lions, armadillos the size of small cars, sloths the size of elephants, beavers the size of bears, and many others were all gone by about 10,000 years ago.
