可用于人类遗骸直接测年的方法包括放射性碳、U系列、电子自旋共振（ESR）和氨基酸消旋（AAR）。这篇综述介绍了这些方法的背景下，测年人类的骨骼和牙齿。超滤技术的最新进展扩大了放射性碳定年的范围。现在似乎可以可靠地将骨骼的年代确定为55，000年。激光烧蚀质谱法的新发展允许对U系列同位素进行原位分析，从而提供了一种快速和几乎非破坏性的测年方法，可以追溯到大约30万年前。这在与非破坏性ESR分析结合使用时尤为重要。AAR分析中的新方法可能会导致这种方法的复兴。这些直接测年技术的潜力和目前的局限性进行了讨论的网站有关重建现代人类的进化，包括弗洛里斯巴德，边境洞穴，塔本，Skhul，Qafzeh，Vindija，Banyoles，蒙戈湖。(c)2006 Wiley-Liss，Inc.
The methods that can be used for the direct dating of human remains comprise of radiocarbon, U-series, electron spin resonance (ESR), and amino acid racemization (AAR). This review gives an introduction to these methods in the context of dating human bones and teeth. Recent advances in ultrafiltration techniques have expanded the dating range of radiocarbon. It now seems feasible to reliably date bones up to 55,000 years. New developments in laser ablation mass spectrometry permit the in situ analysis of U-series isotopes, thus providing a rapid and virtually non-destructive dating method back to about 300,000 years. This is of particular importance when used in conjunction with non-destructive ESR analysis. New approaches in AAR analysis may lead to a renaissance of this method. The potential and present limitations of these direct dating techniques are discussed for sites relevant to the reconstruction of modern human evolution, including Florisbad, Border Cave, Tabun, Skhul, Qafzeh, Vindija, Banyoles, and Lake Mungo.
