USGS Loc. 13740, Americus LS member, Foraker LS formation (Carboniferous of the United States)

Where: Chase County, Kansas (38.4° N, 96.4° W: paleocoordinates 2.2° S, 28.4° 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 was late Carboniferous. The collection comes from the lower limestone 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

• limestone composed almost completely of stromatolites (algae).
