在巴西皮奥伊州塞拉达卡皮瓦拉国家公园的Toca da Bastiana岩棚的一幅岩壁画上发现了方解石层。热释光和EPR测年的方解石给出的年龄为35至43万年,表明人类生活在那里之前的35万年前。这一结果支持的放射性碳年代范围高达48 ka BP较早发现这个网站。
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.
