Bed No. 8, Soldado Rock (Eocene of Trinidad and Tobago)

Where: Trinidad and Tobago (10.2° N, 62.0° W: paleocoordinates 8.3° N, 55.4° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Boca de Serpiente Formation, Priabonian (38.0 - 33.9 Ma)

• STRATIGRAPHIC RELATIONS: From unnamed lithostratigraphic unit. Presumably underlies supposed Oligocene beds. AGE: Early Eocene, based on authors suggestion of "basal Eocene", correlations to Midway Eocene beds and Clayton, Georgia. STRATIGRAPHIC POSITION: From bed 8, near top of section.

•JA: assigned to the (new) Boca de Serpiente Formation and said to be "uppermost Eocene, namely Ludian" = Priabonian by Maury 1929

• bed-level stratigraphic resolution

Environment/lithology: open shallow subtidal; lithified, green, red ironstone

• ENVIRONMENT: Shallow marine carbonate setting.
• SPECIFIC LITHOLOGY: Indurated rock, stained red with hematite and greenish and purplish with other forms of iron. LITHIFICATION: Lithified, based on facies description and figured specimens.

Size class: macrofossils
