700 ft W of Brighton Pier (Miocene of Trinidad and Tobago)

Where: Trinidad and Tobago (10.3° N, 61.6° W: paleocoordinates 9.7° N, 57.9° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Early/Lower Miocene (23.0 - 16.0 Ma)

• STRATIGRAPHIC RELATIONS: From unnamed lithostratigraphic unit. Presumably overlies Eocene (said to be basal Eocene) beds, and is in turn regionally overlain by Miocene through Pleistocene strata. AGE: Oligocene, and probably Late Oligocene, although correlated by the author to the "Chipolan" (=Chipola Fm of Florida, Early Miocene) in age, so perhaps younger than author suggested. Here assigned to Early Miocene on the basis of faunal composition. STRATIGRAPHIC POSITION: From unknown position within regional section.

• bed-level stratigraphic resolution

Environment/lithology: coastal; lithified tar

• ENVIRONMENT: Shallow marine siliciclastic setting.
• SPECIFIC LITHOLOGY: Preserved within asphalt. LITHIFICATION: Lithified, based on facies description and figured specimens.

Size class: macrofossils

Preservation: cast, mold/impression
