Where: Cowley County, Kansas (37.3° N, 96.5° W: paleocoordinates 3.1° S, 29.1° W)
• outcrop-level geographic resolution
When: Americus Limestone Member (Foraker Limestone Formation), Noginian (301.2 - 300.2 Ma)
• The authors placed the Americus Limestone in the Permian, but more recent data indicates that it was late Carboniferous. The collection comes from the upper and middle limestones of the Americus and the shale bed separating them at this locality. The Noginskian stage is recognized as equivalent to the Virgilian Stage.

Environment/lithology: marine; gray limestone and calcareous shale
•20) Shale, very calcareous, tan;
•19) Limestone, hard, dense, dark-gray, weathers blocky; fusulinids abundant; crinoid columnals common;
