Where: Peru (15.9° S, 74.2° W: paleocoordinates 16.0° S, 73.5° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

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

• STRATIGRAPHIC RELATIONS: From the "Huacllaco beds", for which lithostratigraphic relations are not discussed.
