Where: Jamaica (18.3° N, 77.2° W: paleocoordinates 17.2° N, 76.5° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Brown's Town Limestone Member (Moneague Formation), Early/Lower Oligocene (33.9 - 28.4 Ma)

• STRATIGRAPHIC RELATIONS: From the Brownstown Limestone Mbr of the White Limestone Fm, which unconformably overlies the Gibraltar Limestone Mbr (Late Eocene), and is unconformably overlain by the Montpellier Limestone Mbr (Late Oligocene-Early Miocene). STRATIGRAPHIC POSITION: From a band in the lower part the Lepidocyclina undosa/Lepidocyclina favosa zone. LITHOSTRATIGRAPHY: Originally assigned to the Brown's Town Limestone. Replaced by Moneague Formation in Stevens (2004).
