Painted rock art figures from the Boqueirao da Pedra Furada and Toca do Paraguaio shelters (Serra da Capivara, Piaui, Brazil) have been recently analysed using various recognised scientific techniques. After the geochemical results, the samples that revealed carbonate were used for the dating process. Uranium-series disequilibrium dating (U/Th) methods were applied to two of those samples: sample 4 from Toca do Paraguaio (TP04) (a dark red geometric figure), and sample 2 from Toca do Boqueirao da Pedra Furada (BPF2) (a white circular figure). The dates obtained from the U/Th dating provided maximum ages of the paintings. These dates also allowed indirect association of the painting events with the data retrieved from the archaeological excavation. In this paper, we consider, albeit briefly, the archaeological history of the sites and their context into a broader landscape and suggest that geometric figures belong to the early Holocene.

Abstract
Painted rock art figures from the Boqueirao da Pedra Furada and Toca do Paraguaio shelters (Serra da Capivara, Piaui, Brazil) have been recently analysed using various recognised scientific techniques. After the geochemical results, the samples that revealed carbonate were used for the dating process. Uranium-series disequilibrium dating (U/Th) methods were applied to two of those samples: sample 4 from Toca do Paraguaio (TP04) (a dark red geometric figure), and sample 2 from Toca do Boqueirao da Pedra Furada (BPF2) (a white circular figure). The dates obtained from the U/Th dating provided maximum ages of the paintings. These dates also allowed indirect association of the painting events with the data retrieved from the archaeological excavation. In this paper, we consider, albeit briefly, the archaeological history of the sites and their context into a broader landscape and suggest that geometric figures belong to the early Holocene.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
