Where: Hardin County, Illinois (39.0° N, 90.6° W: paleocoordinates 9.1° S, 29.3° W)

• coordinate based on political unit

• outcrop-level geographic resolution

When: Fraileys Shale Formation, Pendleian (330.9 - 327.0 Ma)

• the Fraileys Shale of Kentucky and Illinois is equivalent to the middle Golconda of Indiana; author lists both the Fraileys Shale and Haney Limestone as present at this locality, but gives no further explanation of the stratigraphic nomenclature as to how this is possible [JA: originally entered as "Middle Chester"; the Fraileys Shale and Haney are more specifically Pendleian]

• formation-level stratigraphic resolution

Environment/lithology: marine; shale and limestone
