双塔遗址是近年来松嫩平原先秦时期最为重要的考古发现,该遗址为建立白城西部乃至科尔沁沙地东部地区汉以前考古学文化的编年序列,廓清相关诸考古学文化的谱系关系,奠定了重要基础;为判断同类遗存年代提供了重要标尺,特别是东周时期人骨标本的发现,是迄今在科尔沁沙地东部地区发现的唯一一份保存较为完整的人骨资料。本文对出土9例东周时期的颅骨(男性6例,女性3例)进行了体质人类学的研究,该组颅骨在种族特征上可归入现代亚洲蒙古人种中的北亚人种范围。在若干古代和现代对比组中,双塔组东周时期居民的体质特征与井沟子东周时期居民、近代蒙古人最为接近,属于先秦时期我国北方地区的"古蒙古高原类型",佐证了这一时期该地区的人口流动。
This paper reports on an anthropometric study of human remains recovered from the Shuangta site (2500 BP), a Bronze Age cemetery site located in the western part of Jilin Province. In 2007, the site was excavated jointly by the Research Center for Chinese Frontier Archaeology of Jilin University and the Institute of Cultural Relics and Archaeology of Jilin. It is estimated that the cemetery is dated between late stage of the Spring and Autumn period and early stage of the Warring States period based on artefacts, shapes of the tombs and radiocarbon dating. The radiocarbon dating was conducted by the AMS Lab of Peking University and the charcoal from the II M14 was dated to 2420+35 BP (half-life period of 14C is 5568 BP). The skeletal specimens are unique in the east district of Khorchin Sand Land at present and plays an important roles in studying the ancient racial type and also becomes an gauge in studying the archaeological culture in this region. These specimens were collected from the tombs of Phase 3 belongting to the East Zhou period and are relatively rare in Northeast China. Even more importantly, the East Zhou period is an important time that the nomadic people of the Mongolian Plateau immigrated to the south. This movement brought changes to archaeological culture, technology and life style. Those specimens from the Shuangta site filled the void and changed the situation that there were no human remains in this period. Nine ancient human skulls (6 males, 3 females) unearthed from the Shuangta site were studied. The physical age of the specimens is estimated from skeletal indicators, primarily pubic symphyseal morphology and relative dental wear, and the sex is determined primarily on the basis of the pelvic form and some features supplemented by the crania. Non-metric traits are as follows: cranial shape is ovoid; superciliary arch is strong among males and weak among females; structure of cranial vault sutures is simple. Males shows strong mastoid process while the female is weak. The
