CAS Loc. 325A, between Chorrera and Cibarco [Tubará Fm] (Miocene of Colombia)

Where: Atlántico, Colombia (10.8° N, 75.0° W: paleocoordinates 10.5° N, 73.5° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Tubará Formation, Late/Upper Miocene (11.6 - 5.3 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), suggested to be Early Pliocene based on more recent biostratigraphic correlations, but placed in Late Miocene by enterer on the basis of faunal composition. STRATIGRAPHIC POSITION: From horizon P.

• 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
