Where: Piura, Peru (4.5° S, 81.3° W: paleocoordinates 12.3° S, 109.9° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Talara Shale Member (Talara Formation), Bartonian (41.3 - 38.0 Ma)

• Regarded as lower Upper Eocene on the basis of faunal similarity. Foraminifera suggest an upper Eocene age. Olsson states that the Talara and Saman rocks can be referred to the Upper Eocene and in terms of the European section, to the Bartonian and Ludian.....respectively? In most places the Talara Formation can be divided into three members, a lower shale (Talara Shale), a middle sandstone (Talara Sandstone), and an upper shale (Pozo Shale). In a complete section the Talara Formation has an average thickness of about 2800 ft. Collection is from lower Talara Shale.

• group of beds-level stratigraphic resolution

Environment/lithology: offshore; lithified, gray, cherty/siliceous shale

Size class: macrofossils

Collection methods: quarrying,

• No museum repositories are reported, but material may presumably be the AMNH of PRI collections. Because of uncertaintly this field is left ommited.
