Mammoths and Mastodons, extinct relatives of modern elephants, roamed much of North America until the end of the last Ice Age, 10,000 years ago. TUSKS!: Ice Age Mammoths and Mastodons tells the story of these fabulous creatures, and some of their close relatives and neighbors, as revealed by fossil discoveries and current research. Fundamentally grounded in current research, the exhibit also explores questions of scientific interest today. Did humans play a role in the extinction of North American proboscideans? How do we determine the diets of the ancient giants? Can we reconstruct the climates and ecosystems in which they lived? Visitors leave with new knowledge about fossil proboscideans and an appreciation of science as an ongoing process.
