Where: Elk County, Kansas (37.6° N, 96.6° W: paleocoordinates 2.8° S, 29.0° W)
• outcrop-level geographic resolution
When: Americus Limestone Member (Foraker Limestone Formation), Noginskian (301.2 - 300.1 Ma)
• The authors placed the Americus Limestone in the Permian, but more recent data indicates that it was late Carboniferous. The collection comes from the middle limestone bed of the Americus at this locality. The Noginskian Stage is recognized as equivalent to the Virgilian Stage.
• bed-level stratigraphic resolution
Environment/lithology: marine; gray limestone
