The Chainman Formation is a geologic formation in Nevada. It preserves fossils dating back to the Carboniferous period.
The Ohio Shale is a geologic formation in Ohio. It preserves fossils dating back to the Devonian period.
The Sonyea Group is a geologic group in the northern part of the Appalachian Basin. It preserves fossils dating back to the Devonian period.
The Java Formation is a geologic formation in Kentucky, New York, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia. It preserves fossils dating back to the Devonian period. The formation comprises the Pipe Creek Shale, Wiscoy Sandstone Member in New York, and Hanover Shale Member except in Tennessee.
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 Newcastle Sandstone is a geologic formation in Wyoming, United States. It preserves fossils dating back to the Late Cretaceous period.
The Dunderberg Shale is a geologic formation in Nevada and Utah.
The Chainman Shale is a geologic formation in Utah, mostly identical to the White Pine Shale. It preserves fossils dating back to the Carboniferous period.

The Nanushuk Group or Nanushuk formation is a geologic group in Alaska in westernmost National Petroleum Reserve in Alaska (NPR-A). Oil in these rocks likely was generated beneath Western North Slope and migrated northeastward into NPR-A. It preserves fossils dating back to the Cretaceous period. Underneath the Nanushuk lies the Torok Formation.
The Messel Formation is a geologic formation in Hesse, central Germany, dating back to the Eocene epoch. Its geographic range is restricted to the Messel pit. There it unconformably overlies crystalline Variscan basement and its Permian cover (Rotliegend) as well as Eocene volcanic breccias derived from the basement rocks. The formation mainly comprises lacustrine laminated bituminous shale renowned for its content of fossils in exceptional preservation, particularly plants, arthropods and vertebrates.
Cordylodus is an extinct genus of conodonts in the family of Cordylodontidae.
