Pampa del Palo Terrace (70 m) (Pleistocene of Peru)

Also known as P.164

Where: Moquegua, Peru (17.6° S, 71.2° W: paleocoordinates 17.6° S, 71.2° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Pampa del Palo Terrace Formation, Late/Upper Pleistocene (0.1 - 0.0 Ma)

• Pampa del Palo terrace. From morpho-stratigraphic unit T7. Assigned to MOI stage 9. Late Pleistocene age

• bed-level stratigraphic resolution

Environment/lithology: marine

• Bed within relatively thick vertical stack of shallow-marine, coastal and lagoonal deposits. The Pampa del Palo terrace is interpreted as a fault block that moved independently of the remaining Peruvian coast and, for some time between the end of Middle Pleistocene (before 220 ka) and the early late Pleistocene (ca 120 ka), it rose more slowly or was even down-faulted relative to the rest of the southern Peruvian margin. The independent block movements ceased after substage 5e when the Pampa del Palo terrace was incorporated into the regional uplift of the area.

Size class: macrofossils

Collection methods: quarrying,

• Specimens presumably held in repository given that they were collected and used for aminostratigraphic analyses. Possibly held at Universidad de Atnofagasta (Chile), Museo Nacional de Ciencias Naturales (Spain), Universidad de Salamanca (Spain) or Universidad Complutense (Spain).
