Sta. 59 - Lares [Lares Limestone] (Oligocene of Puerto Rico)

Where: Puerto Rico (18.3° N, 66.9° W: paleocoordinates 17.6° N, 65.9° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Lares Limestone Formation, Late/Upper Oligocene (28.4 - 23.0 Ma)

• STRATIGRAPHIC RELATIONS: From the Lares Limestone which regionally overlies the Collazo Shale and is overlain by the Aguadilla Limestone, and is laterally related to the Ponce chalky beds (Late Oligocene). Correlatable to the Las Cahobe and Thomonde Fm (Haiti), Anguilla Fm (Anguilla), upper Culebra Fm (canal zone), and Tampa Fm (Florida). AGE: Late Oligocene based on macro- and microfaunal biostratigraphy. STRATIGRAPHIC POSITION: From unknown position within formation.

• bed-level stratigraphic resolution

Environment/lithology: lithified limestone

• ENVIRONMENT: Shallow carbonate setting.
• SPECIFIC LITHOLOGY: Limestone. LITHIFICATION: Lithified, on the basis of taphonomic data.

Size class: macrofossils

Preservation: cast, mold/impression
