Goldsboro - Yorktown Formation (Pliocene of the United States)

Where: Wayne County, North Carolina (35.4° N, 78.0° W: paleocoordinates 35.4° N, 77.3° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

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

• Local section name: Goldsboro. Basinal/regional section name: Wayne.

•No specific lithostratigraphic details or stratigraphic relationships provided in text beyond the following: The beds assigned to the Yorktown are grouped for convenience into units lettered A to F, A being the lowest and F being the highest. Collections from Greene county appear to derive from Unit E. Unit E presumably falls within zone 2 of the Yorktown Fm (Gardner 1943). How this equates to the lithostratigraphic members applied in Ward (1992) is unclear. While older literature assigns the Yorktown Formation to the Late Miocene, a late Early Pliocene-Late Pliocene age is assigned to the collection following Ward (1992). Furthemore as the collection is derived from the upper zone of the formation a Late Pliocene age is assigned.

• formation-level stratigraphic resolution

Environment/lithology: coastal; unlithified, shelly/skeletal, gray sandstone

• No geologic or paleoenvironmental data reported in text.
• Gray sand containing many entire and broken shells.

Size class: macrofossils

Reposited in the USNM

• Collections reposited in USNM and USGS collections.
