Where: Beaufort County, North Carolina (35.4° N, 76.8° W: paleocoordinates 35.4° N, 75.9° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Yorktown Formation (Chesapeake Group), Zanclean (5.3 - 3.6 Ma)

• most fossils "are derived from the lower beds of the Yorktown Formation" (McLellan 1983) and the "total thickness of the Yorktown exposure is 15 m" (Snyder et al. 1983)

•Strontium dating places the base of the Yorktown Formation at 4.9 Ma [55]. The top of the Yorktown Formation at Lee Creek Mine is no younger than the middle of the Orionina vaughani ostracod assemblage zone, originally dated to ca. 3.7 Ma [53]. This is roughly in agreement with the top of nannoplankton zone NN14 (3.9 Ma) [20, 54], the second of the three nannoplankton zones correlating with the Orionina vaughani zone [53]. Taken together, these observations indicate an age bracket of 4.9–3.9 Ma. (Marx & Fordyce, 2015)

• member-level stratigraphic resolution

Environment/lithology: estuary or bay; unlithified, blue, argillaceous, muddy sandstone

Size classes: macrofossils, mesofossils, microfossils

Preservation: original phosphate

Collection methods: bulk, salvage, surface (float), sieve

• "Most [large] fossils are collected by prospecting the spoil piles" (McLellan 1983) but forams were collected through bulk sampling and washing with detergent and not acid (Snyder et al. 1983)
