Where: United Kingdom (53.0° N, 1.3° W: paleocoordinates 15.7° N, 14.2° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Changhsingian (254.0 - 252.3 Ma)

• A 4-foot-thick Permian breccia overlies, unconformably, Carboniferous Coal measure Sandstone. This is overlain by alternating sandstones and shales of the Lower Permian Marl, containing ill-preserved plant remains. The top of the cutting exposes the Lower Magnesium Limestone, which here is arenaceous and gritty, obsuring a clear demarcation between this and the lower Permian marl.

• bed-level stratigraphic resolution

Environment/lithology: marine; micaceous, yellow, argillaceous sandstone

Size classes: macrofossils, microfossils

Preservation: original sporopollenin

Collection methods: bulk, chemical,
