The North Branch Formation is a geologic formation in Yukon. It preserves fossils dating back to the Cretaceous period.
Toxolophosaurus was a sphenodont from the Early Cretaceous-age Kootenai Formation of Montana.
The Peedee Formation is a geologic formation in North and South Carolina. A marine deposit, named for exposures along the Great Peedee River, it preserves belemnites and foraminifera fossils dating from the Late Cretaceous. The formation is notable for its occurrence of Belemnitella americana, known as the Pee Dee Belemnite (PDB), a long-standing standard in stable carbon isotope research.
The Tuscaloosa Formation is a geologic formation in Alabama. It preserves fossils dating back to the Cretaceous period.
The Coleraine Formation is a geologic formation in Minnesota. 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 Del Rio Clay is a geologic formation in Texas. 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 The Benton classification is obsolete in some regions, having been replaced by the ascending sequence Graneros Shale, Greenhorn Limestone, and Carlile Shale.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 Loon River Formation is a geologic formation in Northwest Territories. It preserves fossils dating back to the Cretaceous period.
The Ettrain Formation is a geologic formation in Yukon. It preserves fossils dating back to the Carboniferous period.
The Laberge Formation is a geologic formation in Yukon. It preserves fossils dating back to the Jurassic period.
The Jungle Creek Formation is a geologic formation in Yukon. It preserves fossils dating back to the Permian period.
The Aksala Formation is a geologic formation in Yukon. It preserves fossils dating back to the Triassic period.
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 Pender Formation is a geologic formation in British Columbia. It preserves fossils dating back to the Cretaceous period. Organisms that have been recovered from this formation include indeterminate Elasmosaurids, Mosasaurids, and a Chelonioidean, as well as the sea turtle Desmatochelys and the Mosasaurine Kourisodon.
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 Nanaimo Group is a geologic group in both British Columbia and Washington state. It preserves fossils dating back to the Cretaceous period.
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 Cuvieri-Pläner Formation is a geologic formation in Germany. It preserves fossils dating back to the Cretaceous period.
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.
