USGS Loc. 13434, Unit C, Hughes Creek Shale member, Foraker LS formation (Carboniferous of the United States)

Where: Brown County, Kansas (39.9° N, 95.7° W: paleocoordinates 1.2° S, 27.1° W)

• outcrop-level geographic resolution

When: Hughes Creek Shale Member (Foraker Limestone Formation), Noginskian (301.2 - 300.1 Ma)

• The authors placed the Hughes Creek Shale in the Permian, but more recent data indicates that it is late Carboniferous. The collection comes from the lower part of unit C of the Hughes Creek at this locality. The Noginskian Stage is recognized as equivalent to the Virgilian Stage.

• bed-level stratigraphic resolution

Environment/lithology: marine; micaceous, gray, sandy claystone

• Claystone, sandy, micaceous, gray, blocky; shale parting in upper and middle parts; brachiopod zone 1.6 ft. beneath top and at the base of the shaly zone
