The Maligne Formation 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 consists primarily of argillaceous limestone and calcareous mudstone, and was named for the Maligne River in Jasper National Park by P.W. Taylor in 1957.[1][2]
The formation is fossiliferous and includes remains of brachiopods, crinoids, gastropods, cephalopods, and other marine animals, as well as traces made by burrowing organisms.[1]
