"Beginning in 2019, we have undertaken a programme of recording and dating of parietal imagery in Southeast Sulawesi, resulting in the documentation of 44 sites (including 14 new localities), and the dating of 11 individual rock art motifs at 8 sites (Fig. 1). The dated motifs comprised seven hand stencils, and four other paintings (two of human figures and two non-figurative, geometric motifs)."
"We used a new method of U-series dating (LA-U-Series analysis) reported elsewhere5 to obtain age estimates for calcium carbonate deposits that had formed in association with these rock art motifs. In all cases, we obtained minimum ages for the parietal images by dating calcite materials that had formed directly on top of the rock art through natural calcium carbonate precipitation."
A programme beginning in 2019 recorded parietal imagery at 44 Southeast Sulawesi limestone karst sites, including 14 new localities. Eleven rock art motifs at eight sites were dated, comprising seven hand stencils, two human figures, and two non-figurative geometric paintings. LA-U-Series (laser-ablation U-series) analysis was applied to calcium carbonate deposits formed in association with the motifs to estimate ages. Minimum ages were obtained by dating calcite that formed directly on top of the imagery, while maximum ages were sometimes obtained by dating calcite layers immediately beneath the imagery. The results extend the regional record of Pleistocene parietal art beyond Maros-Pangkep into Southeast Sulawesi caves.
