Cueva Tixi - Holocene (Holocene of Argentina)

Where: Buenos Aires, Argentina (38.0° S, 58.0° W: paleocoordinates 38.0° S, 58.0° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Holocene (0.0 - 0.0 Ma)

• Fossil material comes from a depth 0,50-0,75 , corresponding to artificial levels 12 to 16.

Environment/lithology: cave; lithology not reported

• It is a small cave carved in rocks of the La Tinta Formation (Palaeozoic), with an area of 40 sq. m and an internal height of 1.60 m

Size classes: macrofossils, mesofossils

Reposited in the MLP

Collection methods: quarrying,

• Excavation of a 1 sq. m quadrangle. Artificial levels were excavated each 0.05m to a depth of 0,80 m. Depth was taken with respect to an arbitrary zero level. The first 0.20 m, corresponding to the first four artificial levels, were not taken into consideration in the analysis assuming that they might present disturbances.
