Where: Pottawatomie County, Kansas (39.4° N, 96.4° W: paleocoordinates 1.3° S, 27.9° 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 limestone of unit 1 of the Hughes Creek at this locality. The Noginskian Stage is recognized as equivalent to the Virgilian Stage.

Environment/lithology: marine; argillaceous limestone
