Where: Staffordshire, United Kingdom (52.6° N, 2.1° W: paleocoordinates 0.8° S, 7.8° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Westphalian A (318.1 - 314.6 Ma)

• Middle Coal Measures (binds between the "Brooch" and "Thick" coals). Westphalian A, communis chronozone according to Legg et al., 2012.
