Where: Craven County, North Carolina (35.0° N, 77.0° W: paleocoordinates 35.1° N, 76.5° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: James City Formation, Early/Lower Pleistocene (2.6 - 0.8 Ma)
• Basinal/regional section name: Neuse River.
•Sample 1 collected from ~0.5 m above the base of the section and ~0.2 m below Sample 2. James City Fm was regarded as Pliocene by DuBar and Solliday (1963), though more recent biostratigraphy indicates an Early Pleistocene age (DuBar et al. 1974, Blackwelder 1981, McCartan et al. 1982). The James City Fm is considered time equivalent or slightly younger than the Waccamaw Fm of N. and S. Carolina., and with the Caloosahatchee Fm of Florida. Cronin et a. (1984) proposed an age of 1.3-0.7 Ma for the formation.
• bed-level stratigraphic resolution
Environment/lithology: estuary or bay; unlithified, shelly/skeletal, gray, blue, sandy mudstone
Size class: macrofossils
Preservation: original aragonite, original calcite
Collection methods: bulk,
• Counts are specimen tallies corrected to estimate numbers of individual organisms (e.g. for bivalves 1 beak fragment = 1/2 individual). Because of moder of preservation (e.g. dismembered zoaria of fragile bryozoans), abundance of certain organisms given as: A, abundant; C, common; R, rare. Repository unknown, possibly at Humboldt State University.
