Southwest of Ancha Terriza, Rio de los Ciervos (Miocene of Chile)

Where: Chile (53.2° S, 71.0° W: paleocoordinates 54.0° S, 64.0° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Early/Lower Miocene (23.0 - 16.0 Ma)

• Age given as Eocene, but should be early Miocene. The Patagoniense transgression has been dated as early Miocene by Sr isotopes (Cuitiño et al., 2015) and 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).
