Treak Cliff, Castleton (Carboniferous of the United Kingdom)

Where: England, United Kingdom (53.3° N, 1.8° W: paleocoordinates 6.4° S, 1.6° E)

• coordinate based on political unit

• outcrop-level geographic resolution

When: Bee Low Limestones Formation, Asbian (340.0 - 336.0 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; lithified, gray lime mudstone

• consists predominantly of grey to pale-grey calcarenitic limestones...during asbian times, a micritic apron-reef facies formed extensive fringing mudbanks on the flanks of this platform [a shallow marine shelf or platform limestone].

Size class: macrofossils
