2002年，在日本本州岛最北端的青森县东鸟村的滨崎步贝壳堆中发掘出一具6-7岁的人类儿童骨架。该遗址的年龄被评估为中世纪时期（约200年）。600-700年BP）从考古学背景。本研究旨在通过与日本其他人群的比较，特别是与阿伊努人和中世纪日本人的相似性，来研究哈马人骨骼的牙齿（公制和非公制）的形态特征。哈马舍尔德骨骼的牙齿大小在阿伊努人和梅迪人的范围内 * 980-8575 4-1电子邮件：suzk@anat.dent.tohoku.ac.jp ©2004日本人类学会28 Anthropol。Sci.（J-Ser.）eval日语。由于两个对照样本之间的牙齿大小没有显着差异，因此无法显示是否类似于阿伊努人或中世纪日本人。然而，就非韵律牙冠特征而言，哈马人儿童的铲形上切牙发育较弱，显示出它与绳纹土著人和阿伊努人有密切的亲缘关系。在较低的第二乳磨牙中出现中三角嵴，这在绳纹当地人中经常发生，也表明与阿伊努人相似。
In 2002, a human child skeleton of 6–7 years old was excavated from the Hamashiriya shell-mound, Higashidori-mura, Aomori Prefecture, which is located in the northernmost part of Honshu Island, Japan. The age of the site was evaluated at the medieval period (ca. 600–700 yrs BP) from the archaeological background. This study aims to examine the morphological characteristics of teeth, metric and nonmetric, of the Hamashiriya skeleton by comparing them with other populations in Japan, especially focusing on resemblance to the Ainu and the medieval Japanese. The tooth size of the Hamashiriya skeleton is in the range of both Ainu and medi* 980–8575 4–1 E-mail: suzk@anat.dent.tohoku.ac.jp ©2004 The Anthropological Society of Nippon 28 Anthropol. Sci. (J-Ser.) eval Japanese. Since there is no significant difference in dental size between the two control samples, it cannot be shown whether to resemble Ainu or medieval Japanese. In regard to non-metrical crown characteristics, however, the weakly-developed shovel-shaped upper incisors of the Hamashiriya child exhibit that it has close affinities to Jomon natives and Ainu. The presence of middle trigonid crest in the lower second deciduous molar, which frequently occurs in Jomon natives, also indicates the resemblance to Ainu.
