Planktonic foraminifera and calcareous nannofossils recovered from Pungo River Formation sediments in Onslow Bay permit correlation of three stratigraphic sections, each of which approximates a third-order coastal onlap event, with standard ages: Frying Pan Section = middle Burdigalian, Onslow Bay Section = Langhian, and Bogue Banks Section = upper Serravallian. Integrated foraminiferal and nannofossil data also provide biostratigraphic constraints for some fourth-order seismic sequences: FPS-1 and FPS-2 = lower Zone N6, FPS-6 = upper N6 to lower N7, OBS-2 and OBS-3 = mid N8 to upper N9, and BBS-1 to BBS-5 = N12 through N14. The durations of hiatuses between successive third-order sections are approximately 1.0 to 1.5 Ma, whereas those between fourth-order sequences cannot be resolved biostratigraphically.
