Where: Peru (14.5° S, 76.0° W: paleocoordinates 16.6° S, 69.2° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Otuma Formation, Early/Lower Oligocene (33.9 - 28.4 Ma)

• STRATIGRAPHIC RELATIONS: From the Otuma Fm, which regionally is unconformably overlain by the Prisco Fm (late Early Miocene to Late Pliocene). AGE: Eocene/Oligocene in text, on the basis of K/Ar dates, siliceous microfossil zonation, and molluscan biostratigraphy. Here assigned to Early Oligocene consistent with other collections from formation. STRATIGRAPHIC POSITION: From sandstone beds in unknown part of formation.

• bed-level stratigraphic resolution

Environment/lithology: coastal; poorly lithified sandstone

Size class: macrofossils

Preservation: original aragonite
