Аннотация:Animal remains from Paloma, a Preceramic site in the Chilca Valley occupied between 7800 and 4700 B.R, indicate that marine resources were primary to animal-based subsistence. In the Paloma material, terrestrial vertebrates and terrestrial invertebrates contribute 10% of the estimated biomass, whereas marine vertebrates and invertebrates contribute 90% of the biomass. This stratified site offers evidence for subsistence change, but the focus on marine resources did not change. Vertebrates of warm- temperate waters are common in the Paloma assemblage and more common than at Peruvian coastal sites farther north at this same time. Decline in anchovies between 5300 and 5100 B.R coincides with the brief presence of warm-tropical animals and increase in diversity. At approximately 4700 B.R, there is another decline in anchovies, an increase in high-trophic-level fishes, and a decrease in diversity. Data are consistent with the end of the warmer, more humid Hypsithermal around 5000 B.P.
