Where: Jamaica (17.9° N, 76.3° W: paleocoordinates 17.9° N, 76.3° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Late/Upper Pleistocene (0.1 - 0.0 Ma)

• Mitchell et al. (2000) obtained electron spin resonance measurements from corals in the Port Morant Formation on the southeast side of Port Morant Harbour that indicate deposition was during latest Oxygen Isotope Stage 6 to, probably, earliest Oxygen Isotope Stage 5e, that is, last interglacial.

Environment/lithology: perireef or subreef; lithified, shelly/skeletal packstone
