UWYMV Collections

The UWYMV houses approximately 11,800 specimens in four separate collections: mammals, birds, reptiles and amphibians, and fish. In addition, the museum is home to a growing collection of tissues and anatomical parts (e.g. stomach contents, syrinxes).

Most of the historical specimens come from the Great Plains and Rocky Mountains. Additional significant historical collections come from the eastern and southern areas of the United States. State of the art facilities in the museum’s new home in the Berry Center have provided the UWYMV with large amounts of additional collections space, and the museum is currently undergoing rapid expansion in all areas.

The most common specimen types are skins and pelts, skeletons, and fluid preserved whole organisms. The bird collection also contains a small collection of eggs and nests, and a growing collection of spread wings. 

The UWYMV is actively seeking salvage from both Wyoming and Colorado to add to both our modern research and teaching collections. Information on donating specimens to the UWYMV can be found on our donation page.


Access to the UWYMV collections is by appointment only, and there are no public hours for the museum. Use of the collection is granted to researchers, students, classes, and other visitors by contacting museum staff.

Researchers interested in requesting a specimen loan should consult our loan policies page for further information.
