Geographic coverage of mammalian species is worldwide but Carnegie Museum of Natural History’s collection’s strength is in North American material.
The collections from Pennsylvania and West Virginia are among the best in the world, and there are mammals from all 50 states. Holdings from the eastern Arctic are the best of any United States museum and include the holotype (specimen used to describe a new species) of a freshwater seal.
Recent acquisitions from Belize, Bonaire, Curaçao, Costa Rica, Dominica, El Salvador, Grenada, St. Vincent and the Grenadines, Guatemala, Honduras, Jamaica, Mexico, Puerto Rico, and Trinidad and Tobago augment historical specimens from Central America.
