【Abstract】 Forty items of 70 modern Tibetan adult skulls (male 48 , female 22) collected in Naqu dis-trict of Xizang Zizhiqu were measured. Sixteen indexes were calculated and cranial, frontal, gnathic, orbital, nasal and palatal type were defined according to the indexes. There were signifi-cant differences in the measured values between Tibetan skulls and the skulls of Han and Zhuang nationalities. Both sexes had the similar basic characteristics of cranial types. The tapeinocrany in Tibetan skulls amounted to as high as 82% and the chamaecrany in Tibetan skulls more than 52%. These results showed that the characteristics of Tibetan skulls were short and bread. Be-sides, hypsiconchy amounted to more than 67% and chamaerrhiny and hyperchamaerrhiny as high as 73%. It can be concluded that there are significant differences in skulls of Tibetan, Han and Zhuang nationalities.更多还原
