全新世晚期，出现了一系列新技术（单件鱼钩、拨动式鱼叉、木板独木舟等）。被认为大大提高了加州沿海居民的捕鱼能力。单片鱼钩也许是这些文物中最常见的，似乎与海洋捕捞的区域集约化和人口增长时期有关。确定单件鱼钩的古老性因各种埋藏学和方法学因素而变得复杂。因此，这些人工制品最初出现的年龄估计范围从大约5500到2500 cal-bp。为了帮助澄清这种重要的人工制品类型的年代，我们有八个可能最古老的贝壳鱼钩在该地区AMS放射性碳年代。这些日期表明，单片贝壳鱼钩出现在整个南部和中部加州海岸至少2500 cal-bp。我们的数据说明了实用程序的直接AMS测年的个人文物作为一种方法，记录网站的干扰（生物扰动，历史土地利用等）。并完善文物、遗址和区域年表。
Abstract During the Late Holocene, a number of new technologies (single-piece fishhooks, toggling harpoons, plank canoes, etc.) are thought to have significantly enhanced the fishing capabilities of California coastal peoples. The single-piece fishhook, perhaps the most common of these artifacts, appears to correlate with a regional intensification of marine fishing and a period of increased population growth. Determining the antiquity of the single-piece fishhook has been complicated by a variety of taphonomic and methodological factors. Consequently, age estimates for the initial appearance of these artifacts range from about 5500 to 2500 cal- bp . To help clarify the chronology of this important artifact type, we had eight of the potentially oldest shell fishhooks in the region AMS radiocarbon dated. These dates indicate that the single-piece shell fishhook appeared throughout the southern and central California Coast by at least 2500 cal- bp . Our data illustrate the utility of direct AMS dating of individual artifacts as a method of documenting site disturbances (bioturbation, historical land use, etc.) and refining artifact, site, and regional chronologies.
