Geography

| Coordinates: | 17.6° South, 71.2° West (view map) | ||
| Paleocoordinates: | 17.6° South, 71.2° West | ||
| Basis of coordinate: | based on nearby landmark | ||
| Altitude: | 25 meters | ||
| Geographic resolution: | small collection |
Time
| Period: | Quaternary | Epoch: | Pleistocene |
| Stage: | Late/Upper Pleistocene | 10 m.y. bin: | Cenozoic 6 |
| Key time interval: | Late/Upper Pleistocene | ||

Stratigraphy
| Formation: | Pampa del Palo Terrace | ||||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: Pampa del Palo terrace. From morpho-stratigraphic unit T8 and m5. Assigned to MOI stage 7. Late Pleistocene age | |||||
Lithology and environment
| Primary lithology: | poorly lithified "siliciclastic" |
| Includes fossils? | Y |
| Environment: | marine indet. |
| Geology comments: 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. | |
Taphonomy
| Modes of preservation: | body |
| Size of fossils: | macrofossils |
Collection methods and comments
| Collection excludes: | some macrofossils |
| Collection methods: | selective quarrying,field collection |
| Reason for describing collection: | biostratigraphic analysis |
| Collection method comments: 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). | |
| Taxonomic list comments:Not representative. Only includes taxa used for aminostratigraphic analyses. | |
