Where: Wales, United Kingdom (53.0° N, 3.0° W: paleocoordinates 9.7° S, 0.2° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Gronant Group, Tournaisian to Tournaisian (358.9 - 330.9 Ma)

• The sequence exposed consists of about 8 metres of thinly-bedded, dark grey limestones belonging to the Gronant Group (previously the Upper Black Limestone Group). In these sedimentary rocks, land-plant fossils are closely associated with fossils of marine animals, and Walton regarded this as evidence that the strata were lagoonal or shallow marine

• group of beds-level stratigraphic resolution

Environment/lithology: terrestrial; gray limestone

Preservation: adpression
