A calcite formation was found on a rockwall painting at Toca da Bastiana rockshelter at Serra da Capivara National Park, Piaui, Brazil. Thermoluminescence and EPR dating of this calcite gave an age of 35 to 43 ka, indicating that humans lived there prior to 35 ka ago. This result supports the radiocarbon dates ranging up to 48 ka BP found earlier for this site.
