The Museum of Paleontology provides the facilities enabling direct hands-on study of plants and animals preserved as fossils, and study of the environmental, ecological, and paleogeographical conditions in which they lived. These can be studied statically at fixed times in the past or present, and dynamically as they are seen to change through evolutionary and geological time. Because of the Museum and what it facilitates in terms of hands-on experience, our teaching and research programs have long been known for their empirical focus, with an emphasis on testing new ideas as well as generating them.
The Museum is located in the Ruthven Natural History Museum building at 1109 Geddes Avenue, across the street from the C.C. Little Building where the Department of Earth and Environmental Sciences is located.
