This paper reviews the possible approaches for dating of human bones and teeth, older than 500,000. years. Skeletal tissues can, in principle, be dated with an open-system U-series approach, which requires that the Th/U activity ratio is still below equilibrium. This indicates that the sample experienced continuing U-uptake. To gain insights about the state of U-series isotopes in old samples, laser ablation ICP-MS analysis was used for the detailed mapping of U-series isotopes in a 1.2. Ma old...[Show more]
