Extinct American Mammals of the Ice Age
Miniature models of mammoths and other ice-age mammals are depicted in two small dioramas at the entrance to the Hall of North American Mammals. One of the remarkable things about ice-age North America was the number of large predators and scavengers.
Although some of the large mammals in these dioramas resemble animals alive today, all of the ones illustrated are extinct for reasons that may include overhunting, climate change, massive meteor impact, emerging diseases, or a combination of factors.
