记者从海南省文物考古研究院获悉，由中国科学院古脊椎动物与古人类研究所、海南省文物考古研究院、中山大学组成的联合考古队，在2024年度的南或 河流域旧石器考古专项调查中，新发现旧石器地点30处，其中至少有8处地点观察到原生地层。 联合考古队相关负责人介绍，虽然总体上各地点的石制品原料较为相似，但也发现由于南或河流域上下游基岩的不同，使得河流砾石呈现出一定的差异， 导致上下游不同地点的原料种类和丰富度也有所不同。总体而言，石制品具有典型的中国南方砾石工业的特点，同时又包含典型的和平文化特征。据了 解，和平文化指的是东南亚中石器时代至新石器时代早期的文化，是狩猎采集人群向定居人群过渡阶段的一种独特的石核工具文化。 比较而言，调查所得各地点石制品的文化面貌与发掘点BN1所获石制品面貌特征一致，已知其年代学数据可早至距今1.4万年。这是海南地区目前发现的 遗址数量最多、单个遗址面积最大、石制品数量和文化内涵最丰富、年代最老的旧石器时代旷野遗址群。 值得注意的是，部分调查地点经解剖仍保留有原生地层，为下一步在流域内系统开展考古发掘与研究提供了重要的信息基础和工作方向。从各调查点采集 石制品的技术分析研究南或河流域该阶段的 ...

Core Insights - The excavation of the Xicheng Mountain site in Shanxi Province has yielded 494 stone artifacts, providing critical new materials for studying the evolution of stone tool technology, survival behaviors, and adaptation strategies of prehistoric humans in high-altitude environments [1][2] Group 1: Excavation Findings - The site was first discovered in 2006 at an altitude of 1888 meters, with systematic excavations conducted from May to August 2022 by Shanxi University and local cultural heritage institutions [1] - Artifacts are categorized into two stratigraphic units: the lower layer contains 35 pieces dating back approximately 28,000 years, while the upper layer has 459 pieces from a slightly later cultural period [1] Group 2: Material and Cultural Insights - The majority of the stone artifacts were made from high-quality black flint, sourced from a location about 30 kilometers north of the site [1] - The site features a distinctive stone tool type known as boat-shaped cores, which share cultural similarities with the nearby Xiaochuan site, indicating a connection in fine stone tool technology [1][2] Group 3: Research Implications - The new findings from the Xicheng Mountain site contribute significantly to the understanding of fine stone tool culture in the Qinhe River basin, shedding light on the migration patterns of late Pleistocene humans and their adaptation to high-altitude environments [2]
