USGS Loc. 13793, Five Point LS member, Janesville Shale formation (Carboniferous of the United States)

Where: Butler County, Kansas (37.6° N, 96.6° W: paleocoordinates 2.8° S, 29.0° W)

• coordinate based on political unit

• outcrop-level geographic resolution

When: Five Point Limestone Member (Janesville Shale Formation), Noginskian (301.2 - 300.1 Ma)

• The authors placed the Five Point Limestone in the Permian, but more recent data indicates that it is late Carboniferous. Collection comes from the upper limestone of the Five Point at this locality. Noginskian Stage recognized as equivalent to the Virgilian stage.

• bed-level stratigraphic resolution

Environment/lithology: marine; gray limestone

• Limestone, medium-hard, dark-gray, weathers to large blocks; Fusulinid tests common in the limestone
