Lane exposure in Mylett Road, 1.3 km east of Llanddowror (Ordovician of the United Kingdom)

Also known as Loc. 8

Where: Wales, United Kingdom (51.8° N, 4.5° W: paleocoordinates 43.5° S, 18.1° W)

• coordinate based on political unit

• outcrop-level geographic resolution

When: Shelly Zone 4 brachiopod zone, Sholeshook Formation, Cautleyan (449.5 - 445.6 Ma)

• formation-level stratigraphic resolution

Environment/lithology: shelly/skeletal, argillaceous, cherty/siliceous limestone

• The deposits of the Keisley Limestone generally are interpreted to represent a carbonate mud mound.
• "The formation is typically an argillaceous-calcareous or arenaceous-calcareous rock (often not a true limestone), easily weathered to rottenstone and characterised by a particularly rich and varied trilobite fauna with abundant cystoids and brachiopods also." (Price, 1973, Geol. J. 8(2)).
