USGS Loc. 13838, Americus LS member, Foraker LS formation (Carboniferous of the United States)

Where: Lyon County, Kansas (38.5° N, 96.3° W: paleocoordinates 2.1° S, 28.3° W)

• outcrop-level geographic resolution

When: Americus Limestone Member (Foraker Limestone Formation), Noginskian (301.2 - 300.1 Ma)

• The authors placed the Americus Limestone in the Permian, but more recent data indicates that it is late Carboniferous. The collection comes from the middle limestone bed of the Americus at this locality. The Noginskian Stage is recognized as equivalent to the Virgilian Stage.

• member-level stratigraphic resolution

Environment/lithology: marine; limestone

• Fusulinid tests are common in the limestone.
