    An integrative study of new environmental and cultural data from the Hoabinhian of Laang Spean Cave (Cambodia) including modern human remains
    (Elsevier B.V., 2024-10-01)
    Although the Hoabinhian culture is renowned for its unifacial pebble tools and its discovery dates back more than a century, only a handful of sites provide complete information on this period. The site of Laang Spean, in Cambodia, has recently been described as a burial cave for the Neolithic period, but it was previously known as an emblematic Hoabinhian site for Cambodia. More comprehensive studies indicate that it offers a wide window onto the settlement of the Hoabinhian between 12900 and 5000 cal BP. The archaeological layer of the Hoabinhian culture at Laang Spean include faunal, human and lithic remains that enrich our understanding of the environment and way of life of this ancient culture. The faunal assemblage, dominated by bovines, tortoises, molluscs, and cervids, reflects a diverse ecosystem and the adaptability of the Hoabinhian people. The presence of both humid and dry forest indicators, alongside significant wetland areas, suggests their ability to exploit a variety of habitats. The lithic assemblage, characterized by a lower representation of unifaces and greater use of split cobbles, reflects a continuity in basic lithic reduction strategies with minor diachronic changes in raw material selection and tool production, possibly reflecting technological adaptations and increased intensity of occupation. The discovery of human remains, though challenging to contextualize precisely, contributes to understanding settlement patterns and cultural links in prehistoric Southeast Asia. The new data allow for a deeper interpretation of the environmental adaptations and hunting strategies of the Hoabinhian people, including their responses to climatic changes, such as the end of the Younger Dryas. This enhanced knowledge significantly contributes to our comprehension of the environmental dynamics and subsistence practices in prehistoric Southeast Asia and underscores the necessity of reassessing key Hoabinhian sites with modern excavation and dating techniques.

    Technological variability in the Hoabinhian: the example of slab lithic production from the Doi Pha Kan site (Northern Thailand)
    (Elsevier BV, 2025-02-12)
    This research examines the unique lithic technology at the Doi Pha Kan site dated 13 300 to 12 800 calBP in Northern Thailand during the Hoabinhian period (which globally extends from the final Late Pleistocene to Mid Holocene) by means of a technological and morpho-metric analysis. While it shares similarities with typical Hoabinhian assemblages, significant deviations in reduction methods, targeted tool types, and the singular presence of reduction sequences dedicated to the production of a diversity of slab tools. Nevertheless, the study blanks the existence of a distinct population within the Hoabinhian world, indicating a shift towards lighter, composite tools, which may represent a modern trajectory or the final phase of the Hoabinhian culture. The study also ­explores the potential influence of climatic fluctuations at the end of the Late Pleistocene on human behaviors and the evolution of modern human diversity in Southeast Asia. However, due to limited available paleoenvironmental data and data with a few seasonal contrasts in the tropics within a world without winter, a direct connection remains elusive for the moment. The study underscores the need for further research and interdisciplinary collaboration for comprehensive understanding of human paleoecology in the region as well as innovative technical adaptation.
