The Westgate Formation is a geologic formation in Alberta. It preserves fossils dating back to the Cretaceous period.
Rhacolepis is an extinct genus of ray-finned fish from the Cretaceous Santana Formation of Brazil. Complete fossilised hearts from this species have been recovered.
Athabascasaurus is an extinct genus of platypterygiine ophthalmosaurid ichthyosaur known from Alberta, Canada.
The Tuscaloosa Formation is a geologic formation in Alabama. It preserves fossils dating back to the Cretaceous period.
The Windrow Formation is a geologic formation in Minnesota named after Windrow Bluff on Fort McCoy, Monroe County, Wisconsin. It preserves fossils dating back to the Cretaceous period.
The Edwards Group is a geologic group in Texas. It preserves fossils dating back to the Cretaceous period.
The Benton Shale is a geologic formation in Montana, Wyoming, North Dakota, South Dakota, Colorado, Kansas, and Nebraska. It preserves fossils dating to the Cretaceous Period. The term Benton Limestone has also been used to refer to the chalky portions of the strata, especially the upper beds of the strata presently classified as Greenhorn Limestone. The Benton classification is obsolete in some regions, having been replaced by the ascending sequence Graneros Shale, Greenhorn Limestone, and Carlile Shale.
The Etherington Formation is a geologic formation in Alberta. It preserves fossils dating back to the Carboniferous period.
The Blood River Sandstone is a geologic formation in Alberta. It preserves fossils dating back to the Cretaceous period.
The Brazeau Formation is a geologic formation in Alberta. It preserves fossils dating back to the Cretaceous period.
The Waipiabi Formation is a geologic formation in Alberta. It preserves fossils dating back to the Cretaceous period.
The Blairmore Group, originally named the Blairmore Formation, is a geologic unit of Early Cretaceous age in the Western Canada Sedimentary Basin that is present in southwestern Alberta and southeastern British Columbia. It is subdivided into a series of formations, most of which contain plant fossils. In some areas it contains significant reservoirs of natural gas.
The Monach Formation is a geologic formation of Early Cretaceous (Valanginian) age in the Western Canada Sedimentary Basin that consists primarily of sandstone. It is present in the northern foothills of the Canadian Rockies and the adjacent plains in northeastern British Columbia.
The Hulcross Formation is a geologic formation in the Western Canada Sedimentary Basin in northeastern British Columbia that was deposited in marine environments during the late Albian stage of the Early Cretaceous period. At one time considered to be a member of the Commotion Formation, it was elevated to formation status by D.F. Stott in 1982. It preserves ammonites and other fossils.
The Monteith Formation is a geologic formation of Early Cretaceous (Valanginian) age in the Western Canada Sedimentary Basin that consists primarily of sandstone. It is present in the northern foothills of the Canadian Rockies and the adjacent plains in northeastern British Columbia and west-central Alberta.
The Beaver Mines Formation is a stratigraphic unit of Early Cretaceous (Albian) age in the Western Canada Sedimentary Basin that is present in southwestern Alberta and southeastern British Columbia, Canada. It was established by G.B. Mellon in 1967 who named it for the hamlet of Beaver Mines, Alberta. It contains a variety of plant fossils.
The Boulder Creek Formation is a geologic formation in northeastern British Columbia. It was named for a tributary to Commotion Creek in the Pine Pass area by E.M. Spieker in 1921. At one time considered to be a member of the Commotion Formation, it was elevated to formation status by D.F. Stott in 1982.
The Durlston Formation is a geologic formation in England. Particularly in the Isle of Purbeck. It preserves fossils dating back to the Berriasian stage of the Lower Cretaceous.
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 Bickford Formation is a geologic formation of Early Cretaceous (Valanginian) age in the Western Canada Sedimentary Basin that consists primarily of nonmarine sediments. It is present in the northern foothills of the Canadian Rockies in northeastern British Columbia.
Anatolemys is an extinct turtle genus in the family Macrobaenidae. Two species are known, both of which lived in the Late Cretaceous. Fossils were discovered in the Yalovach Formation of Tajikistan, the Kulbikin Member and Khodzhakul and Bissekty Formations of Uzbekistan and the Bostobe Formation of Kazakhstan.
