ABSTRACT

Archaeological data have demonstrated that modern Florida was occupied by at least 14,550 years ago, but evidence of Late Pleistocene and Early Holocene peoples (ca. 14,600–8,000 cal B.P.) is limited to far inland and upland settings, as more than half of Florida’s peninsula was drowned between ca. 21,000–6,000 cal B.P. Rising aquifer levels of the Late Pleistocene allowed some interior sites to preserve within forming river channels, especially some springfed sinkholes that became the Aucilla River of northwest Florida. Terrestrial sites are poorly preserved in comparison, containing stone tools in mixed and/or undateable stratigraphy. Geospatial analysis of the 92 early sites in the Aucilla basin demonstrates that the underwater sites are crucial to provide a more robust understanding of early people, as the earliest sites are found only underwater, and the preponderance of the multicomponent sites also are inundated.

美国佛罗里达州西北部奥西拉盆地的淹没内陆景观:填充晚更新世和早期全新世景观

摘要

考古数据表明,现代佛罗里达州至少在 14,550 年前被占领,但更新世晚期和全新世早期人民(约 14,600–8,000 cal BP)的证据仅限于远内陆和高地环境,佛罗里达半岛的一半以上在大约之间被淹死。21,000–6,000 cal BP 晚更新世含水层水位的上升使一些内部遗址得以保存在形成的河道内,特别是一些成为佛罗里达州西北部奥西拉河的泉水落水坑。相比之下,陆地遗址保存较差,包含混合和/或无法确定地层学的石器。对奥西拉盆地 92 个早期遗址的地理空间分析表明,水下遗址对于更深入地了解早期人类至关重要,
