Abstract:
The dispersal of Homo sapiens across Eurasia during MIS 3 in the Late Pleistocene is marked by technological shifts and other behavioral changes, known in the archaeological record under the term of Initial Upper Paleolithic (IUP). Bacho Kiro Cave in north Bulgaria, re-excavated by us from 2015 to 2021, is one of the reference sites for this phenomenon. The newly excavated lithic assemblages dated by radiocarbon between 45,040 and 43,280 cal BP and attributed to Homo sapiens encompass more than two thousand lithic artifacts. The lithics, primarily from Layer N1-I, exist amid diverse fauna remains, human fossils, pierced animal teeth pendants, and sediment with high organic content. This article focuses on the technological aspects of the IUP lithics, covering raw material origin and use-life, blank production, on-site knapping activities, re-flaking of lithic implements, and the state of retouched lithic components. We apply petrography for the identification of silicites and other used stones. We employ chaîne opératoire and reduction sequence approaches to profile the lithics techno-typologically and explore the lithic economy, particularly blade production methods, knapping techniques, and artifact curation. Raw material analysis reveals Lower Cretaceous flints from Ludogorie and Upper Cretaceous flints from the Danube region, up to 190 km and 130 km, respectively, from Bacho Kiro Cave, indicating long-distance mobility and finished products transport. Imported lithic implements, were a result of unidirectional and bidirectional non-Levallois laminar technology, likely of volumetric concept. Systematic on-anvil techniques (bipolar knapping) and tool segmentation indicate re-flaking and reshaping of lithic implements, reflecting on-site curation and multifaceted lithic economy. A limited comparison with other IUP sites reveals certain shared features and also regional variations. Bacho Kiro Cave significantly contributes to understanding the technological and behavioral evolution of early Homo sapiens in western Eurasia.Keywords:

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.

Most Chinese lithic industries dated between 300,000 and 40,000 are characterized by the absence of Levallois debitage, the persistence of core-and-flake knapping, the rarity of prepared cores, their reduction with direct hard hammer percussion, and the rarity of retouched flakes. Here we report the discovery of seven bone soft hammers at the early hominin Lingjing site (Xuchang County, Henan) dated to 125,000–105,000. These artefacts represent the first instance of the use of bone as raw material to modify stone tools found at an East Asian early Late Pleistocene site. Three types of soft hammers are identified. The first consists of large bone flakes resulting from butchery of large herbivores that were utilized as such for expedient stone tools retouching or resharpening. The second involved the fracture of weathered bone from medium size herbivores to obtain elongated splinters shaped by percussion into sub-rectangular artefacts. Traces observed on these objects indicate intensive and possibly recurrent utilization, which implies their curation over time. The last consists of antler, occasionally used. Lingjing bone tools complement what we know about archaic hominin cultural adaptations in East Asia and highlight behavioural consistencies that could not be inferred from other cultural proxies. This discovery provides a new dimension to the debate surrounding the existence of the Middle Palaeolithic in the region. The attribution of East Asian sites to the Middle Palaeolithic assumes that cultural traits such as the Levallois method represent evolutionary hallmarks applicable to regions of the world different from those in which they were originally found. Here, we promote an approach that consists in identifying, possibly from different categories of material culture, the original features of each regional cultural trajectory and understanding the behavioural and cognitive implications they may have had for past hominin populations.

The technological systems and subsistence strategies of Middle Pleistocene hominins in South-East Europe are insufficiently understood due to the scarcity of well-preserved, excavated assemblages. In this paper, we present first results from the study of the lithic and bone artifacts unearthed at the Lower Palaeolithic site Marathousa 1 (MAR-1), Megalopolis, Greece. The context of the site represents a depositional environment close to a lakeshore, where rapid burial in a very fine-grained matrix ensured extraordinary conditions for preservation. Lithic artifacts occur in spatial and stratigraphic association with remains of the elephant Palaeoloxodon antiquus as well as other mammals. Bones, including those of elephants, show clear anthropogenic flaking scars, cut-marks and fracture patterns indicating deliberate breakage and modification by early humans. The MAR-1 lithic assemblage is composed of small-sized debitage, retouched tools, a few small and exhausted cores, as well as a large number of debris and retouch products, such as chips and resharpening flakes. Currently, there are no indications of Acheulean bifacial debitage, large cutting tools are missing, and a key aspect of the material refers to its 'microlithic' character. The scarcity of cores and primary flakes indicates a fragmented reduction sequence and complex discard patterns that require further investigation. On the basis of the on-going analysis of lithic material from three field seasons, we discuss aspects of assemblage composition and the role of raw material types, the main technological and typological traits of the industry, as well as the potential contribution of the MAR-1 assemblage in broader discussions about Middle Pleistocene lithic techno-complexes and subsistence strategies in Eurasia. Finally, we briefly present a small sample of bone artifacts, which suggest that hominin exploitation of the animal carcasses was not restricted to marrow extraction and bone processing for nutritional needs, but included also the knapping of bones, potentially with the aim of using the knapped products as tools. The MAR-1 archaeological record compares well with other important Eurasian sites yielding 'small tool assemblages', such as Ficoncella, La Polledrara, Bilzingsleben, Schöningen and Vértesszőlős, some of which, like MAR-1, have provided evidence of elephant or other mega-fauna exploitation.

Until recently, several hypotheses on the origin(s) and dispersion of microblade technology in Northeast Asia have been presented and discussed. Although various definitions of microblade and bladelet have been proposed in diverse geographic and chronological contexts, several researchers may agree that the pressure knapping technique for microblade production plays a paramount role in the process of significant changes in lithic technology and human behaviours between marine isotope stages (MIS) 3 and 2. One of the main topics in the study of microblade technology in Northeast Asia is establishing a systematic and reliable method for identifying microblade knapping techniques that are quantitatively verified. This paper attempts to present a more improved method for identifying microblade knapping techniques by dealing with the analysis of fracture wings which are the reliable indicators of the crack velocity. The focus of this paper is on identifying obsidian microblade-like debitage knapping techniques in the Last Glacial Maximum (LGM) assemblage of Kawanishi-C in Hokkaido, Northern Japan. The results of fracture wing analysis show that the microblade-like longitudinal debitage production at the Kashiwadai-C site was employed by not pressure but percussion techniques. This gives new insights into the diversity of microblade and microblae-like debitage reduction sequences in the LGM Hokkaido and complex process of significant changes in lithic technology, especially in relation to the emergence of microblade technology. In addition, this study shows that the analysis of fracture wings can allow appropriate technological evaluation of the microblades and microblade-like longitudinal debitage production in the period before and around the LGM in Northeast Asia.
