Port Morant Harbour, unit 0 (Pleistocene of Jamaica)

Where: Jamaica (17.9° N, 76.3° W: paleocoordinates 17.9° N, 76.1° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Old Pera Member (Manchioneal Formation), Early/Lower Pleistocene (2.6 - 0.8 Ma)

• Within the top 2 m of unit 0; "Early Pleistocene" (presumably not early Pleistocene in current sense, following movement of the Plio-Pleistocene boundary)

• group of beds-level stratigraphic resolution

Environment/lithology: transition zone or lower shoreface; lithified siliciclastic sediments

• Old Pera beds were deposited under storm conditions, as indicated by the presence of amalgamated sandstonebeds and fossils preserved in unusual orientations, such as vertical sand dollars
• The Old Pera beds are a siliciclastic unit

Size class: macrofossils

Collected by G.A. Simpson in 1998; reposited in the BMNH
