CAS Loc. 306, Usiacuri village [Tuberá Fm] (Pliocene of Colombia)

Where: Atlántico, Colombia (10.8° N, 75.0° W: paleocoordinates 10.6° N, 74.2° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Tubará Formation, Early/Lower Pliocene (5.3 - 3.6 Ma)

• LITHOSTRATIGRAPHY: From the Tubará Formation, which overlies the Las Pedices Group (Early Miocene), and is overlain by the Galapa Group (Late Miocene). AGE: Early Miocene, according Barrios (1960), but assigned by the enterer to the Early Pliocene based on more recent biostratigraphic correlations. STRATIGRAPHIC POSITION: From unknown position within section.

• bed-level stratigraphic resolution

Environment/lithology: marine; poorly lithified siliciclastic sediments

• SPECIFIC LITHOLOGY: Not stated in text, but apparently siliciclastic. LITHIFICATION: Poorly-lithified-unlithified, on the basis of figured specimens.

Size class: macrofossils
