THE EARLIEST SHELL FISHHOOKS FROM THE AMERICAS REVEAL FISHING TECHNOLOGY OF PLEISTOCENE MARITIME FORAGERS

Abstract

While the North American archaeological record signals the presence of early humans along the northeastern Pacific coast by the Late Pleistocene, we know little about the technological systems employed by these coastally oriented colonizing groups. We here report the discovery of the earliest unequivocal evidence for the use and manufacture of shell fishhooks in the western hemisphere. Four single-piece shell fishhooks dating to the terminal Pleistocene/early Holocene transition (between ~11,300 and 10,700 cal B.P.) have been excavated on Isla Cedros, Baja California, Mexico. One hook is directly dated at 9495 ± 25 B.P. with a marine reservoir–corrected age of 11,165–9185 cal B.P. Radiocarbon ages associated with three other shell fishhooks range between 8900 ± 25 B.P. and 10,415 ± 25 B.P, while median ages for the earliest contexts confirm occupation of the island by at least 12,600–12,000 cal B.P. The stratigraphic levels from which the fishhooks were recovered contained a diverse assemblage of fish remains, including deepwater species, indicative of boat use. Thus, some of the earliest known inhabitants of the Pacific coast of the Americas employed shell hook and line technology for offshore marine fishing at least by the Pleistocene-Holocene transition, if not earlier.
