Where: Jamaica (18.5° N, 77.4° W: paleocoordinates 18.5° N, 77.1° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Falmouth Formation (Coastal Group), Late/Upper Pleistocene (0.1 - 0.0 Ma)

• STRATIGRAPHIC RELATIONS: From the Falmouth Fm, which unconformably overlies the Hope Gate Fm. THICKNESS: Sample collected from 2-4 m of section of unknown thickness. AGE: Late Pleistocene, last interglacial, Sangamonian, ~125,000 yrs bp. STRATIGRAPHIC POSITION: Unknown position with formation.
