距今1.4万年！海南发现30处旧石器地点

Core Viewpoint - A joint archaeological team has discovered 30 new Paleolithic sites in the Nanhou River basin, with at least 8 sites showing original stratigraphy, indicating significant findings for prehistoric cultural studies in southern China and Southeast Asia [1][3][7]. Group 1: Discovery and Findings - The investigation focused on the Nanhou River site, with the main site designated as BN1 and others numbered from BN2 to BN30 based on their discovery order [3]. - A total of 1,191 stone artifacts were collected during the survey, primarily from the first and second terraces along the river's meandering bends, with some found at higher terraces [3]. - The raw materials for the stone artifacts varied, including sandstone, tuff, mudstone, limestone, conglomerate, sedimentary rock, gneiss, quartzite, and quartz, with sandstone and limestone being predominant [3][5]. Group 2: Cultural Significance - The stone artifacts exhibit characteristics typical of southern China's pebble industry while also reflecting features of the Peace Culture, which represents a transitional phase from hunter-gatherer societies to settled communities in Southeast Asia [5]. - The cultural profile of the artifacts from the surveyed sites aligns with those from the BN1 excavation, with known dating extending back to 14,000 years ago, marking it as the largest and most culturally rich Paleolithic site group discovered in Hainan [7]. - Some surveyed locations still retain original stratigraphy, providing a crucial foundation for future systematic archaeological excavations and research in the region, which could shed light on cultural interactions between southern China and Southeast Asia [7].
