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 middle part of Unit C of the Hughes Creek Shale at this locality. The Noginskian Stage is recognized as equivalent to the Virgilian Stage.
