The Belgrade Formation is a limestone geologic formation in North Carolina characterized by limestone coquina mixed with sand, and thinly laminated clays. It preserves fossils dating back to the Paleogene period.
The Cape May Formation is a geologic formation in New Jersey and Pennsylvania. It preserves fossils.
The Alum Bluff Group is a geologic group in the states of Georgia, Florida, and Alabama. It preserves fossils dating back to the Neogene period.
The Tongue River Member is the uppermost geologic member of the Fort Union Formation in Montana, North Dakota, Wyoming. The strata are yellow or light-colored massive sandstones and numerous thick coal beds.
The Lebo Member is a geologic member of the Fort Union Formation in Montana and Wyoming. It preserves fossils dating back to the Paleogene period.
The Park City Formation is a fossiliferous sedimentary formation from the late Permian of Utah, Idaho, Wyoming, and Montana. It is defined by its cherty, gray to pinkish limestone, calcareous siltstone, and cherty sandstone. The rocks in this formation formed along a shallow marine continental shelf and were regularly interrupted by the Phosphoria Formation due to tectonic forces and sea level change.
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.
