-The Illinois Basin covers Illinois, Western Kentucky and Western Indiana.

- Kinkaid Creek part of the Mississippian system, this formation can vary in thickness and composition. In some areas, oil wells have been said to be as thick as 30-90 feet and generally consist of two thirds limestone and one third shale. These formations tend to contain Kinkadia Trigonalis, Triplophyllities Palmatus, and Caninostrotion Variabilis species. These formations were once corals and have been known to have favorable permeability and porosity in some areas, but in less favorable conditions an acidic proppant solution or chemical fracturing process, or both, have been use to increase horizontal draw. The Kinkaid Limestone is part of the Upper Chester Group within the Chester series of the Mississippi Valley system (also called the Mississippian System).

-The Glen Dean Limestone typically overlies Hardinsburg Sandstone formations in anticline oil and natural gas structures. This formation is recognized by the species more predominantly found closer to Tennessee towards Carter County. The most important fossil of the Glen Dean Limestone is the Bryozoan Prismopora Serrulata as it is the most abundant species associated with creating valuable hydrocarbons like crude oil and natural gas. The Glen Dean formation is part of the Middle Chester Group of the Chester Series of the Mississippian System.

- The Renault Limestone is the basal formation of the Chester Series of the Mississippian System and, as such, is classified as the Lower Chester Group. This formation often tends to yield the most extensive fauna. The Renault Limestone oil and gas formation is easily distinguishable from the Ste. Genevieve Limestone by the presence of several species of the Crinoid Talarocrinus and by the absence of Platycrinus Penicillus.

- The Ste. Genevieve Limestone often overlies the St. Louis formations. This formation is often classified as oolitic as it is different from the St. Louis. Ste. Genevieve formations are notably sandy, and conditions exist for great oil and natural gas extraction if favorable porosity and fossilized lifeforms are found. The Ste Genevieve is often associated with, O’hara and Rosiclare oil and natural gas formations, generally located relatively nearby. The structures of this formation are said to be the corals Lithostrotion Proliferum which, in turn, fostered lifeforms such as the Crinoid Platycrinus Penicillus and Rhipidomella Dubia within the oolitic beds. These oil and gas formations are classified as the Meramec Group of the Iowa Series of the Mississippian system

- Warsaw, St Louis, and Salem Limestone formations are recognized as Meramec Group of the Mississippi Valley. These formations are not as distinguishable from one another as others are in the Mississippi System as it pertains to fossil lithology characteristics. The Salem normally contains a noticeable fauna as they are rarely seen in other oolitic limestones. The Warsaw-Salem Formation overlies varying beds from the Keokuk Age. In other words, these formations can be classified as unconformity. The formations are generally composed of coarsely crystalline crinoids, which are more or less a shale. These crinoids rarely contain corals and, as a result, often contain fewer fossils. Species associated with these formations are the brachiopods Spirifer Washingtonensis, Spirifer Lateralis, and Spirifer Keokuk. Others are the Crinoid Talarocrinus Simplex, Blastoid Metablastus Wortheni, and Bryozoan Archimedes. From an oil and gas standpoint, highly kept trade secrets that can be used to increase production are rarely seen in this area. The Salem’s fauna has been thought to be species with Devonian ancestors. These formations are associated with the Meramec Group of the Iowa Series of the Mississippian System.

- The Fort Payne formation is closely associated with the Ullin formations in both shale and limestone. This is mainly a bryozoan-dominated baffle-structure.

- The Chouteau Shale is part of the Mississippian System of Southern Illinois. This shale is a non-fossiliferous formation and has also been referred to as the Springville Shale and Hannibal Shale formations of the Kinderhook Age as they have similar fossilized remains and lithology.
