Abstract: This paper outlines the analysis of 295 well-preserved adult skeletons from the Moguo Cemetery located in the Lintan Mogou Gannan Tibetan Autonomous Prefecture, Gansu Province. This total of skulls included 283 individuals (164 males; 119 females) from tombs of the Qijia culture period, dating 4000-3500 years ago, plus 12 individuals (7 males; 5 females) from tombs of the Siwa culture period, dating 3500 3000 years ago. The results of this morphological study indicates a physical continuity between the Qijia and Siwa residents whereby the groups can be easily identified and classified as modern East Asian Mongoloids. In a comparison of several modern and ancient groups, the ancient Moguo inhabitants clearly represent the northeast Asian Mongoloid group, with southern groups (including the ancient Gansu and Qinghai Huoshaogou) and Zhuang group being more similar.
