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.
