Where: Chile (37.8° S, 73.3° W: paleocoordinates 37.9° S, 72.8° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Tubul Formation, Early/Lower Pleistocene (2.6 - 0.8 Ma)

• LITHOSTRATIGRAPHY: From the Tubul Fm, which is overlies the Ranquil Fm (Late Miocene). AGE: Dated as middle Pliocene (Martínez and Osorio, 1968), late Pliocene (Martínez, 1976), but is regarded as Early Pleistocene in the present publciation, on the basis of macrofossil and microfossil biostratigraphy.
