Levallois approaches are one of the best known variants of prepared-core technologies, and are an important hallmark of stone technologies developed around 300,000 years ago in Africa and west Eurasia 1,2 . Existing archaeological evidence suggests that the stone technology of east Asian hominins lacked a Levallois component during the late Middle Pleistocene epoch and it is not until the Late Pleistocene (around 40,000-30,000 years ago) that this technology spread into east Asia in association with a dispersal of modern humans. Here we present evidence of Levallois technology from the lithic assemblage of the Guanyindong Cave site in southwest China, dated to approximately 170,000-80,000 years ago. To our knowledge, this is the earliest evidence of Levallois technology in east Asia. Our findings thus challenge the existing model of the origin and spread of Levallois technologies in east Asia and its links to a Late Pleistocene dispersal of modern humans.

Xiaochangliang (XCL), located in the Nihewan Basin of North China, is a key archaeological locality for understanding the behavioural evolution of early humans. XCL dates to ca. 1.36 Ma, making it one of the earliest sites in Northeast Asia. Although XCL represents the first excavation of an Early Pleistocene site in the Nihewan Basin, identified and excavated in the 1970's, the lithic assemblages have never been published in full detail. Here we describe the lithic assemblages from XCL, providing information on stone tool reduction techniques and the influence of raw materials on artefact manufacture. The XCL hominins used both bipolar and freehand reduction techniques to manufacture small flakes, some of which show retouch. Bipolar reduction methods at XCL were used more frequently than previously recognized. Comparison of XCL with other Early Pleistocene sites in the Nihewan Basin indicates the variable use of bipolar and freehand reduction methods, thereby indicating a flexible approach in the utilization of raw materials. The stone tools from XCL and the Nihewan sites are classifiable as Mode I lithic assemblages, readily distinguished from bifacial industries manufactured by hominins in Eastern Asia by ca. 800 ka.

Donggutuo (DGT) is one of the richest archaeological localities in the Nihewan Basin of North China, thereby providing key information about the technological behaviours of early hominins in eastern Asia. Although DGT has been subject of multiple excavations and technological studies over the past several decades, few detailed studies on the lithic assemblages have been published. Here we summarize and describe the DGT lithic assemblages, examining stone tool reduction methods and technological skills. DGT dates to ca. 1.1 Ma, close to the onset of the mid-Pleistocene climate transition (MPT), indicating that occupations at DGT coincided with increased environmental instability. During this time interval, the DGT knappers began to apply innovative flaking methods, using free hand hard hammer percussion (FHHP) to manufacture pre-determined core shapes, small flakes and finely retouched tools, while occasionally using the bipolar technique, in contrast to the earlier and nearby Nihewan site of Xiaochangliang (XCL). Evidence for some degree of planning and predetermination in lithic reduction at DGT parallels technological developments in African Oldowan sites, suggesting that innovations in early industries may be situational, sometimes corresponding with adaptations to changes in environments and local conditions.

Abstract: As in many other regions of the world, the Late Pleistocene in China underwent rhythmic changes of climate, which caused some obvious changes in mammalian fauna, natural landscape and human cultural adaptations. This paper is a brief introduction of four representative Late Pleistocene sites in North China, which are dated at periods between Middle and Upper Palaeolithic, and demonstrated common or particular features from geographic and geological aspects, archaeological and environmental characters, and chronological position. A large transformation happened, reflected by culture remains, showing that environmental changes profoundly influenced human behaviour and inspired new forms of culture appearance. This indicates the clear existence of Middle Palaeolithic at least in North China, which became a foreshadowing for the coming Upper Palaeolithic. [Copyright &y& Elsevier]

Usewear analysis has become an essential method for studying function of lithic artifacts. This article discusses experiments and analyses of usewear on quartzite artifacts caused from bone-working. The raw materials were collected from the Wulanmulun Site, Inner Mongolia, north China. Four working motions were involved, including cutting, scraping, drilling, and chopping. Five specimens were selected for a multi-stage experiment. This experiment demonstrates that apparent usewear would occur on the employable location on specimens as follows: 1) mainly large and medium scarring sizes; 2) mainly stepped and feathered terminations, and hinged ones occasionally; 3) continuous and overlapped distributions; 4) heavy rounding on the used edges of specimens. The multi-stage experiment shows that the number of newly produced scars declined with time duration and intensity of usage. The development of rounding shows a non-linear increase from light to heavy. This article intends to establish a reference collection of lithic usewear on Chinese quartzite for archaeological analyses. [ABSTRACT FROM AUTHOR]
