Extreme Mammals: The Biggest, Smallest, and Most Amazing Mammals of All Time

This extraordinary exhibition explores the diversity of mammals, examining the ancestry and evolution of the biggest, smallest, and most amazing mammals that have walked the Earth. Featuring spectacular fossils, vivid reconstructions, taxidermy, and life-like models—including a 15-foot-high model of extinct Indricotherium, the largest land mammal known to date—Extreme Mammals will both surprise and fascinate visitors. They will be introduced to numerous extraordinary creatures ranging from huge to tiny, from speedy to sloth-like, and can compare oversized claws, fangs, snouts, and horns.

Extreme Mammals is organized by the American Museum of Natural History, in collaboration with the California Academy of Sciences, San Francisco; Cleveland Museum of Natural History; and the Canadian Museum of Nature, Ottawa, Canada.
