Elm Grove ( of the United States)

Where: Ohio County, West Virginia (40.0° N, 80.7° W: paleocoordinates 6.1° S, 16.8° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Monongahela "B" freshwater Limestone Member (Pittsburgh Formation), Virgilian (303.4 - 298.9 Ma)

• Stratigraphy originally recorded as "Stephanian" (Carroll et al., 1998). Update: The Pittsburgh Fm. is the lower unit of the Monongahela Group and is entirely within the Virgilian (see, e.g. Eble et al., 2006, pp. 197-222 in GSA Spec. Pap. 399) .

•"The fossiliferous horizon is Limestone “B” of the Pittsburgh Formation of the Monongahela Group (Berman, 1979), which is considered Virgilian in age (Berman et al., 1997)." Kissel (2010)

• bed-level stratigraphic resolution

Environment/lithology: fluvial; limestone

• The deposit preserved at the Elm Grove locality is interpreted as a meander cutoff channel that filled very slowly (Lund, 1972).

Size class: macrofossils

Reposited in the CM

Collection methods: quarrying, surface (in situ), mechanical,
