Simla Formation (original) (raw)

The Simla Formation is a stratigraphic unit of Late Devonian (late Frasnian) age. It is present on the western edge of the Western Canada Sedimentary Basin in the Rocky Mountains and foothills of west-central Alberta and east-central British Columbia. It consists primarily of carbonate rocks and siltstone, and was named for Mount Simla in northern Jasper National Park by D. J. McLaren and E. W. Mountjoy in 1962. The Simla Formation is fossiliferous. It preserves remains of marine animals, and is especially known for its many species of rugose corals.
