Geography
Country:Peru State/province:Moquegua
Coordinates: 17.6° South, 71.2° West (view map)
Paleocoordinates:
Basis of coordinate:based on nearby landmark
Altitude:25 meters
Geographic resolution:small collection
Time
Period: Quaternary Epoch: Pleistocene
Stage: Late Pleistocene 10 m.y. bin: Cenozoic 6
Key time interval: Late Pleistocene
Age range of interval: 0.129 - 0.0117 m.y. ago
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.
