The mammal collection in the Yale Peabody Museums’s Division of Vertebrate Zoology, although small, is worldwide in coverage, and is used principally for teaching. The 5,086 mammal skins (over 720 species) date from the 19th century, and includes several rare and endangered species: the African elephant, black rhinoceros, orangutan, mountain gorilla, red wolf, black-footed ferret and snow leopard. The skeleton collection is likewise small (4,776 specimens representing over 770 species), but historically important, and contains a disproportionate number of large animals, among them one of only 7 complete skeletons of the now extinct quagga, and a large series of buffalo skulls from the 1870s.
