Acarí section, 10-11 m [Pisco Fm] (Pliocene of Peru)

Where: Peru (15.6° S, 74.6° W: paleocoordinates 15.7° S, 73.9° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Pisco Formation, Late/Upper Pliocene (3.6 - 2.6 Ma)

• STRATIGRAPHIC RELATIONS: Presumably from the Pisco Fm. AGE: Late Pliocene in text, on the basis of K/Ar dates, siliceous microfossil zonation, and molluscan biostratigraphy. STRATIGRAPHIC POSITION: From between 10 and 11 m in section.

• bed-level stratigraphic resolution

Environment/lithology: coastal; unlithified, shelly/skeletal sandstone

• ENVIRONMENT: Not discussed in text, but appears to be from shallow marine siliciclastic setting.
• SPECIFIC LITHOLOGY: Sandy coquina. LITHIFICATION: Unlithified based on figured specimens.

Size class: macrofossils

Preservation: coquina
