This article contains a list of fossil-bearing stratigraphic units in the state of North Dakota, U.S.
Chrysochampsa is an extinct genus of alligatorine. Fossils have been found from the Golden Valley Formation of North Dakota and date back to the Wasatchian regional North American faunal stage of the early Eocene. The genus has been proposed to be synonymous with Allognathosuchus at times, but it is now generally accepted that Chrysochampsa is distinct from all other alligatoroids and is its own taxon.
The Killdeer Formation is a geologic formation in North Dakota. It preserves fossils dating back to the Neogene.
The Cannonball Formation is a geologic formation in western North Dakota. It preserves fossils dating back to the Paleogene Period.
The Ludlow Formation is a geologic formation in western North Dakota. It preserves fossils dating back to the Paleogene Period.
The Slope Formation is a geologic formation in western North Dakota. It preserves fossils dating back to the Paleogene Period.
The Tongue River Member is a geologic member of the Fort Union Formation in North Dakota and Wyoming. It preserves fossils dating back to the Paleogene period.
The Deadwood Formation is a geologic formation of the Williston Basin and Western Canada Sedimentary Basin. It is present in parts of North and South Dakota and Montana in the United States, and in parts of Alberta, Saskatchewan, and southwestern corner of Manitoba in Canada. It is of Late Cambrian to Early Ordovician age and was named for exposures in Whitewood Creek near Deadwood, South Dakota. It is a significant aquifer in some areas, and its conglomerates yielded significant quantities of gold in the Black Hills of South Dakota.
The Montana Group is a geologic group in South Dakota. It preserves fossils dating back to the Cretaceous period.
The Harrison Formation is a geologic group in South Dakota and Nebraska. It preserves fossils from the Miocene.
The Minnelusa Formation is a geologic formation in South Dakota. It preserves fossils dating back to the Carboniferous period.
The Ash Hollow Formation of the Ogallala Group is a geological formation found in Nebraska and South Dakota. It preserves fossils dating back to the Neogene period. It was named after Ash Hollow, Nebraska and can be seen in Ash Hollow State Historical Park.
The Batesland Formation is a geologic formation in South Dakota. It preserves fossils dating back to the Neogene period.
The Rosebud Formation is a geologic formation in South Dakota. It preserves fossils dating back to the Neogene period.
The Monroe Creek Formation is a geologic formation in South Dakota. It preserves fossils dating back to the Paleogene period.
The Sharps Formation is a geologic formation in South Dakota. It preserves fossils dating back to the Paleogene period.
The White River Formation is a geologic formation of the Paleogene Period, in the northern Great Plains and central Rocky Mountains, within the United States.
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 Three Forks Shale is a geologic formation in Montana and North Dakota. It preserves fossils dating back to the Devonian period.
The Belle Fourche Formation or Belle Fourche Shale is a fossiliferous early Late-Cretaceous geologic formation classification in Wyoming. Named for outcrops in Belle Fourche River, Wyoming, this unit name is also used in Montana, North Dakota, and South Dakota.
