The Pungo River Formation is a geologic formation in North Carolina. It preserves fossils dating back to the Middle Miocene.
The Pungo River Formation is mined extensively for its phosphorite deposits.
The Eagle Sandstone, originally the Eagle Formation, is a geological formation in Montana whose strata date back to the Late Cretaceous. It is a light to brownish gray to pale yellow-orange, fine-grained sandstone. It contains areas of crossbedding and local shale members. It contains large sandy calcareous concretions. Its thickness varies from 100 to 350 feet due to the lens nature of the individual sandstone layers and local interbedded sandy shale layers.
The Black Creek Group is a geologic group in North Carolina. It preserves fossils dating back to the Late Cretaceous period.
The Chesapeake Group is a geologic group in Maryland, Virginia, Delaware, and North Carolina. It preserves mainly marine fossils dating back to the Miocene and Pliocene epochs of the Neogene period. This group contains one of the best studied fossil record of Neogene oceans in the world. Professional Paleontologists and amateur fossil hunters alike collect from this group intensely. The Calvert Cliffs stretch the length of Calvert County, Maryland and provide the best continuous stretch of the Calvert, Choptank, and St. Marys Formations. Ward (1985) recommended including the Old Church Formation in this group.
The Jackson Group is a geologic group in Arkansas and North Carolina. It preserves fossils dating back to the Paleogene to Neogene period. The area is where the type specimen of Basilosaurus and ancient whale confused to be a reptile was found.
The Cumnock Formation is a Late Triassic-age geologic formation in North Carolina. It is found in the of the Sanford sub-basin of the Deep River Basin, the southernmost of the large Mesozoic basins forming the Newark Supergroup. It is the middle unit of the Chatham Group, overlying the Pekin Formation and underlying the Sanford Formation. Both of these encompassing formations are primarily red sandstone. The Cumnock Formation, on the other hand, represents a sequence of darker lacustrine (lake) or paludal (swampy/marshy) sediments deposited in a tropical climate. These primarily include shales and coal, with some thin layers of coarser sediment such as siltstone and sandstone.
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 Cid Formation is a metavolcanic rock and mudstone geologic formation in North Carolina. It consists of a lower unnamed mudstone member with intermittent volcanic flows and the Flat Swamp Member, which is characterized by pyroclastic flows. It preserves fossils dating back to the Ediacaran period.
The Bear Bluff Formation is a geologic formation in North Carolina. It preserves fossils dating back to the Neogene period.
The Chowan River Formation is a geologic formation in North Carolina. It preserves fossils dating back to the Neogene period.
The Eastover Formation is a geologic formation in North Carolina. It preserves fossils dating back to the Neogene period.
The Pamlico Formation is a geologic formation in North Carolina. It preserves fossils dating back to the Neogene period. The name was suggested by L.W. Stephenson in the North Carolina Geological and Economic Survey journal in 1912
The Pollocksville Formation is a geologic formation in North Carolina. It preserves fossils dating back to the Neogene period.
The Trent Formation is a geologic formation in North Carolina. It preserves fossils dating back to the Neogene period.
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 New Bern Formation is a geologic formation in North Carolina. It preserves fossils dating back to the Paleogene period.
The River Bend Formation is a limestone geologic formation in North Carolina. It preserves fossils dating back to the Paleogene period.
The James City Formation is a geologic formation in North Carolina. It preserves fossils.
The Waccamaw Formation is a geologic formation in southeastern North Carolina and eastern South Carolina. It preserves fossils from the early Pleistocene epoch. The Waccamaw Formation contains two informal members: "upper" and "lower". The upper Waccamaw is ~2.1-1.8 million years old. The lower Waccamaw Formation is ~2.4-2.2 million years old.
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.
The Pocahontas Formation is a coal-bearing geologic formation in West Virginia. It preserves fossils dating back to the Carboniferous period.
