中石器时代(MSA)的现代人类行为创新包括最早的由贝壳贝冢证明的完全沿海适应的指标,但许多MSA贝冢仍然很难确定日期。对南非西开普省YFT 1鸵鸟蛋(OES)进行了230 Th/U埋藏年龄测定。结果表明,YFT 1鸵鸟蛋的230 Th/U埋藏年龄相对精确(中位数± 2.7%),与其它年龄限制条件一致,并保持了地层学的基本原则。贝叶斯年龄-深度模型表明,YFT 1沉积于11.99至11.31万年前(ka)(模型年龄的95% CI),整个3.8米厚的垃圾堆可能是在2.23万年内积累的。OES的稳定碳、氮、氧同位素表明,在被占领期间,当地环境主要由C3植被组成,最初比现在明显湿润,但随着时间的推移变得干燥和凉爽。结合OES ~(230)Th/U年龄和稳定同位素分析表明:1)YFT 1是已知的最古老的贝冢,在120 ka前对贝冢完全适应性的限制最小; 2)尽管在贝冢被占领期间海平面迅速下降和其他气候变化,但贝冢的相对比例和大小保持不变,这表明贝冢适应性觅食沿着不断变化的海岸线; 3)YFT 1石器技术复合体与其他西海岸组合体相似,但与南部非洲海岸沿着潜在的同步工业不同,表明人类种群在季节性降雨区之间分散;(4)积累率(高达1.8米/ka)远高于以前观察到的日期,分层MSA的垃圾坑,这意味着更激烈的网站占领类似于晚石器时代的垃圾坑。
Modern human behavioral innovations from the Middle Stone Age (MSA) include the earliest indicators of full coastal adaptation evidenced by shell middens, yet many MSA middens remain poorly dated. We apply230Th/U burial dating to ostrich eggshells (OES) from Ysterfontein 1 (YFT1, Western Cape, South Africa), a stratified MSA shell midden.230Th/U burial ages of YFT1 OES are relatively precise (median ± 2.7%), consistent with other age constraints, and preserve stratigraphic principles. Bayesian age–depth modeling indicates YFT1 was deposited between 119.9 to 113.1 thousand years ago (ka) (95% CI of model ages), and the entire 3.8 m thick midden may have accumulated within ∼2,300 y. Stable carbon, nitrogen, and oxygen isotopes of OES indicate that during occupation the local environment was dominated by C3vegetation and was initially significantly wetter than at present but became drier and cooler with time. Integrating archaeological evidence with OES230Th/U ages and stable isotopes shows the following: 1) YFT1 is the oldest shell midden known, providing minimum constraints on full coastal adaptation by ∼120 ka; 2) despite rapid sea-level drop and other climatic changes during occupation, relative shellfish proportions and sizes remain similar, suggesting adaptive foraging along a changing coastline; 3) the YFT1 lithic technocomplex is similar to other west coast assemblages but distinct from potentially synchronous industries along the southern African coast, suggesting human populations were fragmented between seasonal rainfall zones; and 4) accumulation rates (up to 1.8 m/ka) are much higher than previously observed for dated, stratified MSA middens, implying more intense site occupation akin to Later Stone Age middens.
