“…Given the chronological ubiquity of this type of ornament in Mongolia, Northern China (e.g. Janz et al, 2009) and in Africa, it is still unclear whether the presence of these beads reflects cultural affinities or convergences. Larger sample size, more detailed analysis and additional chronological data are needed to address these issues.…”

“…OES is reliably dated by the AMS radiocarbon method, and dating OES is appropriate for the 1970-1973 collections housed at the National Museums of Kenya (NMK) because the material is resistant to diagenetic contamination and does not degrade with storage time like charcoal (2,(35)(36)(37)(38). Sample preparation was similar to the procedures of Janz et al (37) and incorporated a strong preanalysis acid etch designed to remove outer surfaces and any associated contamination. To measure reliability further, two OES samples were split and sent to different radiocarbon dating laboratories (University of Arizona and Queen's University Belfast), yielding statistically indistinguishable results for both samples.…”

Kenya National Museums Lukenya Hill Hominid 1 (KNM-LH 1) is a Homo sapiens partial calvaria from site GvJm-22 at Lukenya Hill, Kenya, associated with Later Stone Age (LSA) archaeological deposits. KNM-LH 1 is securely dated to the Late Pleistocene, and samples a time and region important for understanding the origins of modern human diversity. A revised chronology based on 26 accelerator mass spectrometry radiocarbon dates on ostrich eggshells indicates an age range of 23,576–22,887 y B.P. for KNM-LH 1, confirming prior attribution to the Last Glacial Maximum. Additional dates extend the maximum age for archaeological deposits at GvJm-22 to >46,000 y B.P. (>46 kya). These dates are consistent with new analyses identifying both Middle Stone Age and LSA lithic technologies at the site, making GvJm-22 a rare eastern African record of major human behavioral shifts during the Late Pleistocene. Comparative morphometric analyses of the KNM-LH 1 cranium document the temporal and spatial complexity of early modern human morphological variability. Features of cranial shape distinguish KNM-LH 1 and other Middle and Late Pleistocene African fossils from crania of recent Africans and samples from Holocene LSA and European Upper Paleolithic sites.

“…The sites include stone features of unknown function; flaked-stone tools such as the characteristic microblade cores, microblades, unifacial scrapers, projectile points, and bifaces (likely used as axes or adzes), as well as other types of cores, preforms, and debitage; ceramic shards; and ground stone. We note that while the term Neolithic is used here, others have used the terms Epipalaeolithic and Mesolithic for the same types of assemblages (see Wright 2006:23-27;Janz et al 2009;Wright & Janz 2012). The same locations have been used through several chronological periods, as we also find Bronze Age, Iron Age, and more recent artefacts and features on the surface.…”

Abstract:The transition from the Mongolian Neolithic to the Bronze Age is not well understood. Within Ikh Nart Nature Reserve, over a period of five years, we identified a number of sites with dense surface artefact scatters and features that seem to represent this transition period. Evident in those concentrations are characteristic microblade cores, microblades, "thumbnail" flake scrapers, projectile points, ground stone tools, and stone features of unknown function. Between 2012 and 2014 we collected ground stone artefacts from four sites and sediment samples from three sites. With permission of Mongolian authorities, the artefacts from one site and sediment samples from three sites were sent for botanical analyses to the University of Texas, Austin, Environmental Archaeology Laboratory. Preliminary results indicate that plant remains are present on the ground stone artefacts: dendritic long-cells from a deep pore of one artefact and starch grains from the pores of six of the seven artefacts. These data present the first opportunity to understand what resources "Neolithic" people were processing with ground stone tools in this area and further our opportunity to better understand the little-known "Neolithic"-Early Bronze Age transition period in Central Asia. This paper describes the ground stone artefacts and further explores the results of data retrieved from some of these artefacts.
