Where: Bio-Bio, Chile (37.2° S, 73.5° W: paleocoordinates 38.0° S, 68.4° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Ranquil Formation, Burdigalian (20.4 - 16.0 Ma)

• The biostratigraphy of the Ranquil has not been studied in detail, but it is probably the same age as the Navidad Formation. Dating of the Navidad Formation has been debated, but radiometric, strontium, bivalves, and planktonic foraminifera are most consistent with a Burdigalian age (Finger, 2013).
