The Rocky Mountain Group is a geologic group in Alberta. It preserves fossils dating back to the Permian period.
Gravitholus was a genus of pachycephalosaurid dinosaur from the late Cretaceous period. It was a pachycephalosaur, and like other pachycephalosaurids the skull roof formed a thick dome made of dense bone, which may have been used in head-butting contests over mates or territory. It lived in what is now Alberta, Canada, and was described in 1979 by W. P. Wall and Peter Galton. The type species is Gravitholus albertae.
The Conemaugh Group is a geologic group in West Virginia, Pennsylvania, Ohio, and Maryland. It preserves fossils dating back to the Carboniferous period.
The Cincinnati Group is a geologic group in Kentucky, Ohio and Indiana. It is Upper Ordovician.
The Mural Formation is a geologic formation in Alberta. It preserves fossils dating back to the Cambrian period.

The Tunnel Mountain Formation is a geologic formation that is present on the western edge of the Western Canada Sedimentary Basin in the Canadian Rockies of western Alberta. Named after Tunnel Mountain near Banff, it was deposited during the Early Pennsylvanian sub-period of the Carboniferous period.

The Miette Group is an assemblage of metamorphosed sedimentary rocks of latest Precambrian (Neoproterozoic) age. It is present in the Canadian Cordillera from the Lake Louise area of Alberta to the Yukon. The Miette rocks include Ediacaran fossils, stromatolites, and trace fossils.
The Kootenay Group, originally called the Kootenay Formation, is a geologic unit of latest Jurassic to earliest Cretaceous age in the Western Canada Sedimentary Basin that is present in the southern and central Canadian Rockies and foothills. It includes economically important deposits of high-rank bituminous and semi-anthracite coal, as well as plant fossils and dinosaur trackways.
The Spray River Group is a stratigraphic unit of Triassic age. It is present on the western edge of the Western Canada Sedimentary Basin in the foothills and Rocky Mountains of western Alberta. It was originally described as the Spray River Formation by E.M. Kindle in 1924 and was later raised to group status. Its type section is located in the Spray River gorge at the southern end of Sulphur Mountain.
