Mammals of Pennsylvania Online Resource
Which mammals live in Pennsylvania, and where?
The following is a list of the 70 mammals known to live or have lived in Pennsylvania. The list provides common names and currently recognized scientific names. Each mammal is grouped with its closest relatives. Groupings are described in common terms as well as by family or order names. Please click on highlighted names to see information on that mammal.
Maps are shown for each species whose current distribution is known. Some mammals are found throughout the Commonwealth of Pennsylvania. Others have very limited distribution due to such factors as soil requirements, food preferences, or geographic barriers to dispersal. The larger map on each mammal page shows the counties from which specimens are represented in our collection.
Specimens of all these species are found in the research collection of the Section of Mammals at Carnegie Museum of Natural History. However, we do not have Pennsylvania specimens for some of the “long gone” species such as the wolf and the mountain lion.
