The fossil record suggests that at least two major human dispersals occurred across the Eurasian steppe during the Late Pleistocene. Neanderthals and Modern Humans moved eastward into Central Asia, a ...region intermittently occupied by the enigmatic Denisovans. Genetic data indicates that the Denisovans interbred with Neanderthals near the Altai Mountains (South Siberia) but where and when they met H. sapiens is yet to be determined. Here we present archaeological evidence that document the timing and environmental context of a third long-distance population movement in Central Asia, during a temperate climatic event around 45,000 years ago. The early occurrence of the Initial Upper Palaeolithic, a techno-complex whose sudden appearance coincides with the first occurrence of H. sapiens in the Eurasian steppes, establishes an essential archaeological link between the Siberian Altai and Northwestern China . Such connection between regions provides empirical ground to discuss contacts between local and exogenous populations in Central and Northeast Asia during the Late Pleistocene.
Situated between the Altai Mountains and the Chinese Loess Plateau, the current territory of Mongolia played a pivotal role in Pleistocene human population dynamics in Northeast Asia with ...archaeological evidence suggesting the existence of cultural links with southern Siberia beginning in the Late Pleistocene. Here, we present preliminary results from the newly discovered site of Kharganyn Gol 5 in northern Mongolia. The results obtained from the Kharganyn Gol 5 site allow new reconstructions of chrono-cultural sequences and human behavior in eastern Central Asia. The site has yielded evidence of human occupation corresponding to several phases of the regional Upper Paleolithic. In addition, we present the first evidence of human occupation of the region prior to Greenland Interstadial 12 (GI12; 40,000–43,000 BP) and discuss the implications of such data. The Kharganyn Gol River basin contains sedimentary rock formations including numerous raw material outcrops, containing various types of chert. Prehistoric people used all these chert varieties for tool production, but the modes of raw material exploitation changed through time. This paper reports the presence, unique in Central and North Asia, of a non-utilitarian object made of muscovite mica in an Initial Upper Paleolithic assemblage in Archaeological Horizon 5 of the Kharganyn Gol 5 site.
Numerous questions remain regarding the timing and the context of Upper Paleolithic emergence in Northeast Asia. Available data allow the recognition of a form of Initial Upper Paleolithic (IUP) ...documented in the Altai circa 45–40 ka 14C BP, and in the Cis- and Transbaikal around −37 ka 14C BP. In Northern Mongolia, a series of assemblages show intriguing similarities with IUP laminar assemblages from South Siberia and suggest long distance contact/movements of population during the first half of MIS3. These contacts are potentially enabled by the main river that drains into Lake Baikal, the Selenga. By cutting through the Sayan and the Yablonovy mountain ranges, the Selenga drainage system provides a potential corridor connecting South Siberia with the plains of Mongolia. The Tolbor 16 site (Ikh Tulberiin Gol, Northern Mongolia) is located circa 13 km from the confluence with the Selenga. The first results presented here suggest that the lithic assemblage and the ornaments discovered at Tolbor 16 document the early appearance of Upper Paleolithic in the region. This newly discovered site offers the possibility to generate high-resolution contextual data on the first appearance of the blade assemblages in Mongolia and to test the ‘Selenga corridor hypothesis’.
In Central and East Asia, the Upper Paleolithic dates as early as 45 ka cal BP, but until recently, there was little reliable information concerning human occupation during the following period, ...between 45 and 40 ka cal BP. Here we present results of the excavation of the site of Tolbor-21, in the Selenga drainage system, Northern Mongolia. We focus on Tolbor-21 Archeological Horizon 4 (AH4), an archeological assemblage that documents human occupations that fall stratigraphically and chronologically between the Initial and the Early Upper Paleolithic. We report on the spatial distribution of the finds, the zooarcheological and the lithic data to determine which of the observations reflect post-depositional processes, and which are informative of human behavior. Our initial results presented here show evidence of reworking and preservation bias on a succession of occupations, the exploitation of medium/large herbivores, and a potential structured use of space. At the regional level, our results suggest that improving the resolution of data collection may identify previously undocumented episodes of human occupation. At a broader scale, the Tolbor-21 AH4 assemblage brings new perspectives on the development of the Early Upper Paleolithic in Central and Northeast Asia.
•The first evidence of ornament-making at the territory of modern Mongolia dated to Initial Upper Paleolithic.•Drilling was the most common technique of ornament-making in Initial Upper ...Paleolithic.•The first evidence of mica usage is dated to 38,000 years ago.•People could transport “exotic” raw material in 500 km at least.
Little is known about the acquisition and transport of rare or “exotic” raw materials in the Initial Upper Paleolithic (IUP). A recently discovered perforated muscovite (mica) flakelet at the Kharganyn Gol 5 site in the middle Selenga Basin of Mongolia raises the question of how far ancient humans ranged to access this material. Here, we present the initial results of an ongoing study, including dating by 40Ar/39Ar and identification of the muscovite source. The age of the Mongolian muscovite correlates with the Oktyabr’skaya outcrop in the Russian Transbaikal region, >500 km from the site. The Buteeliin Nuruu Mountains, near the Kharganyn Gol 5 site, are geologically similar and potentially contain as-yet unknown muscovite outcrops. This evidence suggests that Initial Upper Paleolithic populations had developed social networks or moved over long distances, using the Upper Paleolithic Selenga Corridor in both cases. Alternatively, the area’s Pleistocene occupants may have known the geological resources of their home range better than we do now.
