Crock Hey opencast pit (Carboniferous of the United Kingdom)

Where: England, United Kingdom (53.5° N, 2.7° W: paleocoordinates 0.1° N, 7.3° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Wigan Four-Foot Coal Formation, Westphalian A (318.7 - 316.9 Ma)

• Langsettian; uppermost Westphalian A, lower Modiolaris chronozone. Concretion-bearing interval present in roof shale overlying Wigan Four-Foot Coal.

• group of beds-level stratigraphic resolution

Environment/lithology: interdistributary bay; lithified, concretionary, sideritic mudstone

• Pennine Basin. The extensional tectonics of the early Carboniferous had been superseded by a phase of thermal subsidence, caused by the cooling of the asthenosphere beneath tectonically thinned lithosphere.
• Siderite concretions in mudstone

Size class: macrofossils

Preservation: mold/impression
