Where: Jamaica (18.3° N, 77.2° W: paleocoordinates 17.1° N, 76.7° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Somerset Formation (White Limestone Group), Late/Upper Eocene (37.2 - 33.9 Ma)

• STRATIGRAPHIC RELATIONS: From the Gibraltar Limestone Mbr of the White Limestone Fm, which overlies the Swanwick Limestone Mbr (Middle-Late Eocene), and is unconformably overlain by the Brownstown Limestobe Mbr (Late Eocene). Approximately equivalent to the upper Troy Limestone Mbr and Someset Limestone Mbr in the central inlier and Machester Plateau of Jamaica. AGE: Late Eocene, based on macrofossil and microfossil biostratigraphy. STRATIGRAPHIC POSITION: From the Phacoides megameris band, which is the lower of two in the Late Eocene of this region. LITHOSTRATIGRAPHY: From the Gibraltar Limestone according to Cox (1941). This unit is now abandoned, and has been replaced by the Somerset Fm.
