Resumen:
Micromammal remains (< 1 kg) from the archaeological sequence of Pomona open-air site (North Patagonia, Negro River) are taxonomically and taphonomically studied. The remains (NISP=814,
MNE=759, MNI=76) were recovered from final Late Holocene layers. The
micromammal assemblage are mainly composed by large-sized (>150 g) taxa (>93%; Microcavia australis, Galea leucoblephara, Ctenomys sp. and Holochilus brasiliensis), to a lesser degree on medium- (50?150 g)
(Reithrodon auritus), and small-sized
(<50 g)
taxa (Akodon dolores and Oligoryzomys longicaudatus). With the
exception of H. brasiliensis, the taxa recorded at Pomona associated with the Monte
desert, and are still present in the area. Dominance of large-sized
micromammals is mostly related with human exploitation. The finding of several
burned remains of the cavies M. australis and G. leucoblephara, and the
marsh rat H. brasiensis, and some cut marks on long bones of cavies, support
this assertion. Evidences of human comsuption on these rodents were also found
in others archaeological sites across the Negro River basin, along with a great
variety of other resources such as large and medium-size vertebrates, and
plants. However, it is important to note that links to the intensification
process must be cautiously considered. Since there is no data from earlier periods, better evaluation of
long-term changes in subsistence strategies should be considered.More diverse diet in
the Negro River would be expected about 1 ka BP, due to the warmer and more
humid general climatic conditions, and because of the higher availability of
resources than in surrounding areas without fluvial systems.
