Individual Identification Analysis of
Dolphin Articulated Vertebras from the Mawaki Site

Tetsuo HIRAGUCHI


This paper discusses 64 examples of dolphin articulated vertebras excavated from 6 ~15m excavation grid (with an additional 1/2‡u for one unit) in Stratum ‡]‡T(c.5000B.P.)Cthe District ‡T at the Mawaki site. My analysis is based on the three proceedings: to@identify as accurately as possible the positions of the subjects in the vertebral series, to measure the greatest length of Corpus vertebrae, the greatest breadth of Fossa vertebrae and the height of Fossa vertebrae , and to examine the degrees of fusion at@the cranial or caudal extremities. The result is that only three sets of articulated@vertebras were identified as those of the same or presumably the same individuals. The humeri pair-matching has shown a similar result. It might reasonably be supposed that@when neighboring settlements worked together in dolphin fishing and yet the catch was@poor for their labor mobilization, it was impossible for a settlement to have a share@of a whole dolphin or that the useful parts divided and then distributed among the settlements were butchered at each settlement, a resulting in the fact that even at dumps near a butchery facing a fishery coast only a@few examples of the same individuals were excavated. My conclusion is consistent with the fact that the ƒÂ‚P‚RC or ƒÂ‚P‚TN values in the human bone collagen at the Mawaki site are little different from those at other Jomon-period sites on the coast of the Main Island.
