Where: Wales, United Kingdom (52.8° N, 3.1° W: paleocoordinates 34.9° S, 16.5° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Rhuddanian to Rhuddanian (443.4 - 438.5 Ma)

• Rhuddanian - Aeronian inferred due to the statement that this age is "pre-Upper Llandovery, in that it is not yet possible...to distinguish the Lower from the Middle Llandovery (Rhuddanian and Idwian) [in this area]."

• bed-level stratigraphic resolution

Environment/lithology: marine
