Lake Pueyrredon (Miocene of Argentina)

Where: Argentina (47.5° S, 71.9° W: paleocoordinates 48.3° S, 66.2° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: El Chacay Formation, Burdigalian (20.4 - 16.0 Ma)

• Presumably from the El Chacay Formation. This unit has been dated as early Miocene (Burdigalian) by Sr isotopes (Cuitiño et al., 2015) and correlative units also as Burdigalian by U-Pb chronology (Cuitiño et al., 2012).

• group of beds-level stratigraphic resolution

Environment/lithology: transition zone or lower shoreface; lithified sandstone

• Brachiopods mostly come from the siltstone to fine sandstone facies, likely transition zone to shoreface (Cuitiño et al., 2015).
• Units are lithified, based on field photos in Cuitiño et al. (2015).
