The Fairholme Group is a stratigraphic unit of Late Devonian (Frasnian) age. It is present on the western edge of the Western Canada Sedimentary Basin in the Rocky Mountains and foothills of Alberta and British Columbia. It was named for the Fairholme Range near Exshaw in the Canadian Rockies by H.H. Beach in 1943.[1][2]
The formations of the Fairholme Group include fossils of marine animals such as stromatoporoids, corals, brachiopods, crinoids, and conodonts.
