Geography

Country:	Jamaica
Coordinates:	17.9° North, 76.3° West (view map)
Paleocoordinates:
Basis of coordinate:	estimated from map
Geographic resolution:	small collection

Time

Period:	Neogene	Epoch:	Pliocene
Stage:	Piacenzian	10 m.y. bin:	Cenozoic 6
Key time interval:	Late Pliocene
Age range of interval:	3.6 - 2.58 m.y. ago

Stratigraphy

Geological group:	Coastal	Formation:	Bowden
Stratigraphic resolution:	bed
Stratigraphy comments: STRATIGRAPHIC RELATIONS: From Pickerill et al. (1998). Bowden Formation is the uppermost stratigraphic unit of the Lower Coastal Group. The top of the formation is defined by the nonconformably overlying, early Pleistocene Old Pera Beds of the Upper Coastal Group. AGE: Late Pliocene. The unit was formely regarded as Miocene in age, even Oligocene, but foraminiferal and planktic gastropod biostratigraphy points to a late Pliocene age. THICKNESS: The formation has an extimated maximum thickness of 150m, although the basal part of the formation is unexposed. STRATIGRAPHIC POSITION: Unknown position within formation. COMMENTS: In its type area of the Bowden district, natural exposures of the formation are poor and discontinuous, so that a complete and detailed stratigraphy of the entire sequence cannot be determined.

Lithology and environment

Primary lithology:	pebbly unlithified conglomeratic marl
Includes fossils?	Y
Lithology description: SPECIFIC LITHOLOGY: Imperfectly consolidated gravel consisting of pebbles and grains of igneous rocks, limestone, and other sorts of rock in a marly matrix. LITHIFICATION: Unlithified, based on observation of specimens.
Environment:	offshore
Geology comments: ENVIRONMENT: The conglomeratic lithofacies are interpretated as a product of sediment gravity flows, more specifically turbidites, and constitute and integral component of the Bowden Shell bed. The marlstone lithofacies is interpreted as a product of pelagic and hemiplegaic deposition from low density turbidity currents, or possibly even bottom water nepheloid layers.

Taphonomy

Modes of preservation:	body,original aragonite,original calcite
Degree of concentration:	concentrated
Size of fossils:	macrofossils
