The Wann Formation is a geologic formation in Kansas and Oklahoma. It preserves fossils dating back to the Carboniferous period.
The St. Clair Limestone is a geologic formation in Arkansas, Indiana, Missouri, and Oklahoma. It preserves fossils dating back to the Silurian period. This high density, high magnesium dolomitic limestone was originally classified as a marble in Oklahoma due to the fact that it would hold a high polish, hence Marble City.
The Chanute Formation is a geologic formation in Kansas, Missouri, and Oklahoma. It preserves fossils dating back to the Carboniferous period.
The Dewey Formation is a geologic formation in Iowa and Oklahoma. It preserves fossils dating back to the Carboniferous period.
The Barneston Formation is a geologic formation in Kansas, extending into Oklahoma and Nebraska. It preserves fossils dating back to the Permian period.
The Fort Scott Formation is a geologic formation in Kansas and Oklahoma. It preserves fossils dating back to the Carboniferous period.
The Seminole Formation is a geologic formation in Kansas and Oklahoma. It preserves fossils dating back to the Carboniferous period.
The Wabaunsee Formation is a geologic formation in Kansas. It preserves fossils dating back to the Carboniferous 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 The Benton classification is obsolete in some regions, having been replaced by the ascending sequence Graneros Shale, Greenhorn Limestone, and Carlile Shale.
