Crude unifacial tools, choppers, and a burin have been uncovered in association with megafauna in a buried stratum that was radiocarbon dated at 12,200 B.C. in a cave in highland Peru. The tool types, megafauna, and date are significant with regard to the problem of the antiquity of man and his culture in the New World.
在秘鲁高地的一个洞穴中，放射性碳测年为公元前 12200 年的埋藏地层中，与巨型动物化石一起出土了原始的单面工具、砍砸器和雕刻器。这些工具类型、巨型动物化石和年代对于解决新大陆人类及其文化的古老性问题具有重要意义。
