Scholars have long recognized the importance of organic artifacts to an improved understanding of the economic and social behavior of Palaeolithic hominins. However, in contrast to archaeological studies in other parts of the world, osseous industries from China have received only limited attention. As one of the first steps aiming at tipping this balance, the current paper examines, therefore, a shaped boar tusk—one particular element of hunter-gatherers' tool kit at Shuidonggou Locality 12 (SDG12). Morphological and metrical comparisons of the tusk with both paleontological specimens and bone artifacts from the same site demonstrate that wear pattern on one of the dentin surfaces of the tooth is not significant different from occlusal attritions in living animals, while linear striations on the other dentin facet are most probably artificial grinding marks formed by prehistoric toolmakers in attempts to manufacture a scraper. The tusk specimen from SDG12 represents the first evidence of a ground tooth in Upper Palaeolithic China. The current study indicates that hominins in Shuidonggou area had achieved a deepened understanding of physical properties of osseous material available in environs and ultimately broadened their range of raw material selection by adding a particular element to the inventory of subsistence tools.

Information on Palaeolithic bone technology from China is sparse. Here we present the results of a techno-functional analysis of a bone tool assemblage recovered from Shuidonggou Locality 12 (SDG12), layer 11, Northern China, dated to c. 12-11 cal ka BP. Six bone tool artefact types are identified: wedges, awls, spear points, a knife handle, a possible sewing implement, and a notched carpal. Two other artefacts could not be attributed to a specific type. The artefacts are made of Procapra przewalsikii , Lepus sp., Sus sp., Equus przewalskii , and unidentifiable bone fragments from medium/large size mammals. At least three methods are used to extract blanks: percussion of altered limb bones, longitudinal splitting of Sus sp. canine and large rib, and probably, the groove-and-splinter technique. Grinding and scraping are the dominant shaping techniques together with grooving, notching, polishing, drilling, flaking, and retouching. Tool type variability and function fit the hypothesis according to which the SDG12 and similar sites would be residential camps in which hunter-gatherers produced artefacts enabling them to cope with cold environmental conditions. Our results, however, indicate that not all bone tools match the expectations associated with a serial specialist production. Expedient wedges and awls may have been produced by any member of the group, and whenever the need arose. The SDG12 bone tool assemblage provides a significant contribution to our knowledge about hunter-gatherer adaptations to the Tardiglacial environments of Northern China. [ABSTRACT FROM AUTHOR]

Seasonality study of Paleolithic archaeological faunal assemblages is important for reconstructing modes of animal death and ancient hominin strategies for prey acquisition. The dental cementum of animal teeth records the season of an individual animal in which it died, providing the necessary evidence for determining any patterns in season of death. This article presents the procedure and preliminary results of the application of cementum incremental analysis to equid teeth, which comprise the dominant component of the fauna from the Xujiayao Site-an early Late Pleistocene archaeological site in China. Results show multi-seasonal use in both the upper and lower layers of this site. Furthermore, attention is given to the method's future application in seasonality studies at Paleolithic archaeological sites in China. [ABSTRACT FROM AUTHOR]

Here we present the results of a techno-functional analysis of 17 bone tools recovered from strata 6, 5 and 3 of the Palaeolithic site of Ma'anshan Cave, Guizhou Province, southern China. Stratum 6, dated to c. 35 cal kyr BP, has yielded three sharp awls. From Stratum 5, dated to c. 34 cal kyr BP, come six probable spear points, awls and a cutting tool. Separated from these layers by a sterile horizon, Stratum 3, dated 23 cal kyr BP to 18 cal kyr BP, has yielded barbed points of two types. Bone tools were shaped by scraping, grinding, and in strata 5 and 3, finished by polishing. Ma'anshan Cave records the oldest formal bone tools from China, and amongst the oldest known evidence of indisputable barbed point manufacture outside Africa. Change in the hunting toolkit between strata 5 and 3 may indicate a shift in prey preference from medium to small size mammals and fish, which needs to be verified by supplementary analyses. The significance of this evidence is discussed in the context of what is known about the origin of bone tool technology in Africa and Eurasia. [ABSTRACT FROM AUTHOR]

The process of the Middle to Upper Palaeolithic transition has been hotly debated for many years, but East Asia has not been a significant part of that debate until recently. The Shuidonggou (SDG) site complex, yielding Initial Upper Paleolithic (IUP) blade-rich assemblages, has been given more and more importance since its discovery and first excavation in the 1920s. This paper presents a specific study of the archaeological remains yielded by three years of systematic, modern excavations at Shuidonggou locality 7 (SDG7), an important locality within the SDG site cluster. Although the archaeological deposits of SDG7 had undergone some hydraulic disturbances, detailed lithic analyses identified two distinct technological systems. One is termed autochthonous and is a predominantly flake-tool technology, and the other is an allochthonous Levallois-like technology which coexisted within the same Lower Concentrated Layer for some time before disappearing, implying the potential existence of technological diffusion and interaction between the two different technologies. The technological variability and change suggested by the evidence from SDG7 reveal a kind of cultural mosaic, rather than the replacement of one lithic technology by another. We believe the new round of excavations and research in the SDG site will provide more evidence for answering key questions about the process of the Middle–Upper Paleolithic transition in North China.
