PRI Loc. 1611 [Yorktown Fm] (Pliocene of the United States)

Where: Isle of Wight County, Virginia (37.0° N, 76.6° W: paleocoordinates 37.1° N, 75.9° W)

• coordinate stated in text

• outcrop-level geographic resolution

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

• STRATIGRAPHIC RELATIONS: From the Yorktown Fm, which unconformably overlies regionally the Eastover Fm (Late Miocene), and is unconformably overlain regionally by the Chowan River Fm. It is unknown from which member of the Yorktown Formation that this collection is derived. AGE: Early to early-Late Pliocene on the basis of known age-range of the Yorktown Formation (Ward, 1992).

• ENVIRONMENT: Shallow marine siliciclastic environment.
• SPECIFIC LITHOLOGY: Medium yellow sand. LITHIFICATION: Unlithified, on the basis of visual inspection of collection.
