Where: York County, Virginia (37.2° N, 76.5° W: paleocoordinates 37.3° N, 75.8° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Moore House Member (Yorktown Formation), Late/Upper Pliocene (3.6 - 2.6 Ma)

• STRATIGRAPHIC RELATIONS: From the Moore House Mbr of the Yorktown Fm, which unconformably overlies regionally the Morgarts Beach and Rushmere Mbrs of the Yorkown Fm, and is unconformably overlain regionally by the Chowan River Fm.

Taxonomic list

• COVERAGE: Not exhaustive (as commented by Ward 1993, p. 3), but includes fairly comprehensive lists of characteristic gastropods and bivalves. NOMENCLATURE: Lists compiled by R. Arnold, based on identifications by Harris, with nomenclature subsequently revised by Ward to a modern standard, with species-resolution assignments.
