315.2 - 323.2 Ma
Age: Pennsylvanian (315.2 - 323.2 Ma)
Stratigraphic Name: Caseyville Formation
Comments: Thickness from stratigraphic columns: Caseyville Fm (0-500’) in southern Illinois (south of 40 degrees north latitude); Caseyville (0-90’) in northern Illinois (north of 40 degrees north latitude). The Caseyville Formation represents the lower part of the Racoon Creek Group. In southern Illinois, the Caseyville Formation includes, from oldest to youngest, the Wayside Sandstone, Battery Rock Sandstone, "Biehl, Buchanan, Jordan, Pottsville, Ridgley", Pounds Sandstone members (and also some unnamed coal beds).
