 note = {application/pdf, 論文(Article), In archaeology, there is a method to determine which season the animal die and how old the animal die by examining the tooth cement and counting its annual layers of excavated animal remains. To examine
why an annual layers is formed in tooth cement, I observed tooth cement of domestic pig from June 2007 to May 2OO8. As a result of observation, there is no annual layers of all them. I concluded that annual layers in tooth cement is limited to a wild animal, and a domesticated animal does not have. The factor of it is regarded as seasonal variation in feeding. Therefore, we can not find an annual layers in tooth cement of past domesticated animal. Though there is a possibility that there is domesticated pig in Jomon and Yayoi period, I could find an annual layers in all archaeological specimens which I examined till now which was found in excavations. Therefore, I thout that there is not domesticated pig in archaeological specimens I examined. But, there is a possibility that there is a wild pig keeped by human in Mutayori site from viewpoint of ratio of age and sex.},
