Where: Pottawatomie County, Kansas (39.3° N, 96.2° W: paleocoordinates 1.5° 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 upper part of unit A consisting of three beds (two limestone and one shale) at this locality. The Noginskian Stage is recognized as equivalent to the Virgilian Stage.
• group of beds-level stratigraphic resolution
Environment/lithology: marine; gray, calcareous siltstone and limestone
•Lower limestone bed: Limestone, medium-hard, sandy, tan, weathers blocky;
•Upper limestone bed: Limestone, medium hard, tan-gray, with gray-green tint, weathers nodular; some clay balls as much as 1/8 inch in diameter.
