Bed No. 2, Soldado Rock [Soldado Fm] (Paleocene of Trinidad and Tobago)

Where: Trinidad and Tobago (10.2° N, 62.0° W: paleocoordinates 7.4° N, 49.2° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Soldado Formation, Thanetian (59.2 - 56.0 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. Assigned to here to the Late Paleocene based on present day biostratigraphic data. STRATIGRAPHIC POSITION: From bed 2, near base of section.

•JA: "equivalent to European Montian and Thanetian of England" = Thanetian according to Maury 1929

• bed-level stratigraphic resolution

Environment/lithology: open shallow subtidal; lithified, shelly/skeletal, gray, red limestone

• ENVIRONMENT: Shallow marine carbonate setting.
• SPECIFIC LITHOLOGY: Extremely hard, greyish-reddish limestone containing quantities of shells which have become an integral part of the rock. LITHIFICATION: Lithified, based on facies description and figured specimens.

Size class: macrofossils
