The challenge of direct dating old human fossils
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]
