史前岩画的绝对年代测定是一项令人兴奋的考古工作。先进的样品收集、处理和预处理方法以及新的分析设备和技术正在最大限度地减少污染，并能够识别史前油漆中的微量有机物质。使用加速器质谱法（AMS）的放射性碳测年法正在为偶然或故意掺入绘画中的血液，木炭和植物纤维的微小残留物产生日期。最近，在岩石艺术之下和之上积累的含碳薄层，如碳酸盐结壳和硅皮，也被确定了年代。
Absolute dating of prehistoric rock paintings is an exciting archaeological pursuit. Sophisticated sample collection, handling and pretreatment methods and new analytical equipment and techniques are minimizing contamination and permitting identification of trace amounts of organic substances in prehistoric paints. Radiocarbon dating using Accelerator Mass Spectrometry (AMS) is producing dates for minute residues of blood, charcoal and plant fibres, either accidentally or deliberately incorporated in paintings. Carbon-bearing laminations, such as oxalate-crusts and silica skins, which have accumulated under and over rock art, have also been recently dated.
