Bolsover Colliery (Carboniferous of the United Kingdom)

Where: England, United Kingdom (53.2° N, 1.3° W: paleocoordinates 0.1° S, 8.2° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Deep Hard Formation, Westphalian A (318.1 - 314.6 Ma)

• from roof of seam 15 cm above coal, at 586 m deep

Environment/lithology: delta plain; lithified siliciclastic sediments

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 The extensional tectonics of the early Carboniferous had been superseded by a phase of thermal subsidence, caused by the cooling of the asthenosphere beneath tectonically thinned lithosphere.

Size class: macrofossils

Preservation: mold/impression
