Where: Lyon County, Kansas (38.7° N, 96.1° W: paleocoordinates 2.1° S, 28.1° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Aspinwall Limestone Member (Onaga Shale Formation), Noginskian (301.2 - 300.1 Ma)

• The authors place the Aspinwall LS in the Permian, but more recent data indicates it is late Carboniferous.

•Noginskian stage is reported as equivalent to Virgilian stage.

• member-level stratigraphic resolution

Environment/lithology: marine; limestone
