Where: Peru (14.2° S, 76.1° W: paleocoordinates 18.0° S, 97.2° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Chilcatay Formation, Late/Upper Oligocene (28.4 - 23.0 Ma)

• STRATIGRAPHIC RELATIONS: From the Chilcatay Fm, which regionally, unconformably overlies the Otuma Fm (Oligocene) and is unconformably overlain by the Pisco Fm (Middle Miocene-Late Pliocene). AGE: latest Oligocene-early Middle Miocene, for which justification is not stated. Overlain by the Prisco Fm, for which K/Ar dates, siliceous microfossil zonation, and molluscan biostratigraphy supports a Middle Miocene age at its oldest. The collection is placed by the authors within the uppermost Oligocene. STRATIGRAPHIC POSITION: From basal sandstone above angular unconformity.

• bed-level stratigraphic resolution

Environment/lithology: coastal; lithified sandstone

Size class: macrofossils

Preservation: original aragonite
