Abstract Thirty-two radiocarbon dates obtained from four archaeological sites in the southern Andean Range of Ecuador are presented in order to contribute toward filling existing chronological and interpretive gaps regarding human occupations in highland South America, mainly during the late Pleistocene to early Holocene transition. These radiocarbon dates, together with nine other dates previously obtained for the studied area, were submitted to significance tests analyses to assess which of them are statistically similar at the intra- and inter-site scales. Pooled mean ages and respective clusters of dates were combined with isolated dates of studied sites, and with artifactual data aiming at producing some initial interpretations regarding micro-regional human dynamics for southern highland Ecuador through time. In the studied area of ~55 km2 diverse anthropogenic scenarios directly linked with proposed chronological stages are briefly described. These activities suggest that local and micro-regional human interaction dynamics were consistent, continuous, and complex through time from 12,000 cal. BP onward.

厄瓜多尔南部高地库比兰地区晚更新世至全新世考古遗址的最新放射性碳数据集

摘要 提供了从厄瓜多尔安第斯山脉南部的四个考古遗址获得的 32 个放射性碳日期，以有助于填补有关南美洲高原人类职业的现有年代和解释空白，主要是在更新世晚期到全新世早期过渡期间。这些放射性碳日期与之前为研究区域获得的其他九个日期一起提交给显着性测试分析，以评估其中哪些在站点内和站点间尺度上具有统计相似性。合并的平均年龄和各自的日期簇与研究地点的孤立日期相结合，并与人工数据相结合，旨在对厄瓜多尔南部高地的微区域人类动态随时间产生一些初步解释。在约 55 平方公里的研究区域中，简要描述了与提议的年代阶段直接相关的各种人为情景。这些活动表明，从 12,000 卡路里开始，局部和微区域的人类交互动态是一致、连续和复杂的。BP 向前。
