佛洞地遗址位于云南省临沧市耿马傣族佤族自治县勐简乡勐简村大军赛村民小组燕子洞，坐落于一处东南开口的二叠纪灰岩穿洞，南临南汀河。2016~2017年，临沧市文物管理所在公路考古调勘期间发现该遗址；为进一步认识滇西地区旧石器时代晚期文化，2017~2018年对该遗址开展考古发掘工作。发掘区域位于洞内第四台面到第五台面间，共发掘20 m²，出土了包括石制品、动植物化石等在内的大量遗物。初步地层年代学分析显示，遗址时代为距今18400~14000年，共包含3期连续文化，文化遗物以石制品为主，总数达到9735件。佛洞地遗址作为一处热带-亚热带生境下的史前遗址，为我们构建旧石器时代晚期滇西地区文化序列、探讨特定自然生态背景下史前人类的文化适应提供了重要参考。

The Fodongdi site is located at Mengjian village, Gengma County, Lincang City, Yunnan Province. It is situated on the north bank of Nanting River, in a Permian limestone cave with an entrance towards southeast. The site was discovered in 2016~2017, and excavated in 2017~2018 by a joint team of the Yunnan Provincial Institute of Cultural Relics and Archaeology, the Institute of Vertebrate Paleontology and Paleoanthropology, Chinese Academy of Sciences and Lincang Prefecture Administration of Cultural Relics, etc. The excavation exposed an area of 20 m². A plenty of remains were unearthed, including lithic artifacts, fauna fossils, and flora fossils. Based on the results of primary sedimentary and chronological analysis, the prehistoric cultural layers were dated back to 18,400~14,000 BP, and divided into three phases. As a prehistoric site located in the tropical-subtropical region, the Fodongdi site provide some new data to interpret the adaptation behavior of prehistory humans in a specific ecological context during Late Pleistocene.
