USGS Loc. 13520, Five Point LS member, Janesville Shale formation (Carboniferous of the United States)

Where: Pottawatomie County, Kansas (39.4° N, 96.2° W: paleocoordinates 1.4° S, 27.8° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

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