“…The p-values of four teeth from the Jianshi cave range between −1 and 0, which indicate a relatively early uptake of uranium in the dental tissues (Figure 3B) (Han et al, submitted). The fossil samples from the youngest Yumidong site show different uranium uptake behaviors which both relatively early and recent uptake history were indicated by p-values (Figure 3E) (Shao et al, 2022). Three fossil samples from the Bailongdong site exhibit early U-uptake history, while the other five experienced U loss based on their U-series data, and the ESR/U-series ages can be obtained only using the AU model (Figure 3D) (Han et al, 2019).…”

“…If the sampling condition permits, applying multiple dating methods to different kinds of dating materials is preferable, and they could complement each other and eliminate the disadvantages and limits due to the assumption or requirement of the methods. The study of the Yumidong site shows clearly the advantages and interests of such multi-methods approach to provide a single unified chronological framework (Shao et al, 2022).…”

“…The cave deposits are mainly composed of brown karstic sandy clay and limestone breccia and the stratigraphic sequence was divided into five layers initially by Wei et al (2017) and further subdivided in detail into 18 layers (Shao et al, 2022). Two fossil teeth and three calcite samples collected from Layer 2, 3 and 4 were dated by the U-series method at the University of Queensland, the tooth sample from Layer 2 gives an age of ~8.4 ka, while another tooth sample and one calcite sample from Layer 3 were dated to ~78.5 ka and ~75.2 ka, respectively.…”

“…To better constrain the chronology of the Yumidong depositional sequence, a multimethod dating study was realized including coupled ESR/U-series analyses on six fossil teeth from L2 to L12, and a Bayesian approach was used to refine the chronostratigraphy of the Yumidong site (Shao et al, 2022). Based on this study, a ~300 ka long history of human occupation in the Yumidong site was established, and it indicates a continuous human settlement in the TGR during cold and warm stages from late Middle Pleistocene to the Late Pleistocene period.…”

The Three Gorges region (TGR) located in the geographic center of China, is a transition zone between mountain and plain areas, and a probable migration corridor for hominins and other mammals between South and North China. Detailed chronological information of paleoanthropological evidence in this area could help us better understand the human evolution in East Asia. The OSL and U-series dating methods are two conventional dating methods generally adopted to date such sites; however, their applications were limited by the dating range—restricted to several hundred of millennia and ambiguous stratigraphic relationship between the archaeological remains and the dating target materials. Cosmogenic nuclide burial dating of quartzite stone artifacts and coupled electron spin resonance and uranium series dating (ESR/U-series) of fossil teeth have the potential to date Early–Middle Pleistocene hominin sites in Asia and were applied increasingly in China in recent years. However, the application of cosmogenic 26Al/10Be burial dating is limited in TGR because most sites are dominated by limestone, leading to the scarcity of the quartz component. In this case, the coupled ESR/U-series method plays a more important role in the establishment of the chronology of human settlement. In TGR, by using the coupled ESR/U-series method, we have dated seven important Early and Middle Pleistocene hominin settlement sites, including Longgupo, Jianshi, Yunxian, Meipu, Bailongdong, Changyang, and Yumidong sites. Based on our dating results, we propose that hominins were settled in TGR probably from the early stage of Early Pleistocene (∼2.5−2.2 Ma) at the Longgupo site to the late Middle Pleistocene to Late Pleistocene of the Yumidong site (∼274−14 ka) and very likely to spread to other parts of East Asia during this time period. In view of the potential of coupled ESR/U-series dating on fossil teeth from the hominin sites in the TGR, future work may consider the micro damage or non-destructive analysis of enamel fragment with the ESR method and laser ablation ICP-MS techniques that will make possible the direct dating of precious human fossils in China.

The application of Zooarchaeology by Mass Spectrometry (ZooMS) on Pleistocene sites in Europe and northern Asia has resulted in the discovery of important new hominin fossils and has expanded the range of identified fauna. However, no systematic, large-scale application of ZooMS on Palaeolithic sites in East Asia has been attempted thus far. Here, we analyse 866 morphologically non-diagnostic bones from Jinsitai Cave in northeast China and Yumidong Cave in South China, from archaeological horizons dating to 150–10 ka BP. Bones from both sites revealed a high degree of collagen preservation and potentially time-related deamidation patterns, despite being located in very distinct environmental settings. At Jinsitai, we identified 31 camel bones, five of which were radiocarbon dated to 37–20 ka BP. All dated specimens correspond to colder periods of Marine Isotope Stages 3 and 2. We regard the presence of camels at Jinsitai as evidence of wild camels being a megafauna taxon targeted, most likely by early modern humans, during their expansion across northeast Asia. This large-scale application of ZooMS in China highlights the potential of the method for furthering our knowledge of the palaeoanthropological and zooarchaeological records of East Asia.
