Cucao, Chiloe Island (Feldmann locality) (Miocene of Chile)

Where: Chile (42.7° S, 74.1° W: paleocoordinates 43.5° S, 68.7° W)

• coordinate estimated from map

• outcrop-level geographic resolution

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

• The biostratigraphy of the Lacui Formation 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).

• group of beds-level stratigraphic resolution

Environment/lithology: marine; lithified siliciclastic sediments

Size class: macrofossils

Preservation: original aragonite
