In November 1998 an international team, sponsored by the National Geographic Society and the Fund for Scientific Research-Flanders (Belgium), conducted a rock art survey in the vicinity of El-Hosh in Upper Egypt. A multitude of sites with thousands o

At many sites throughout the world rock art paintings have been covered by naturally deposited calcite laminations, which we demonstrate can be individually dated by recently improved uranium-series methods. Here we report the application of multi-co

The authors describe rock art dating research in Australia using the oxalate method. While the array of dates obtained (which range from c. 1200 to c. 25 000 BP) show a satisfactory correlation with other archaeological data, there are mismatches whi

We report a test of the dating of oxalate minerals near the radiocarbon limit. Oxalate salts are used for estimating the ages of prehistoric rock paintings and carvings, but uncertainties have existed about the origin of the carbon they contain. Sedi

The dating of land surfaces has long posed problems for geomorphologists. Relative methods (stratigraphic, geomorphic, topographic) are sound and convincing. Exhumed forms may complicate identification and relationships, for both epigene and etch for

Critical to any chronology is reliability in the determination of age for a distinctive artefact that is related to other components in a series. Therefore, the independent testing and verification of the antiquity of an apparent anomalous measuremen

Direct dating, using the Accelerator Mass Spectrometry (AMS) 14C method, indicates that some petroglyphs (rock art) at El-Hosh in Upper Egypt pre-date the early 7th millennium BP (mid 6th millennium cal BC), making it the oldest graphic activity reco
