Also known as Dunkard Locality 9

Where: Monongalia County, West Virginia (39.7° N, 80.2° W: paleocoordinates 5.2° S, 15.7° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Upper Marietta Sandstone Member (Washington Formation), Asselian (298.9 - 295.5 Ma)

Environment/lithology: lacustrine; lithified limestone

• "Fossils were found in a siliceous limestone lens about 15 feet in length which had a maximum thickness of six inches" (Moran, 1952)
