of the Xiongnu of Transbaikalia and the Ordos show commonly show individuals with West Eurasian features. Iaroslav Lebedynsky said that West Eurasian depictions in the Ordos region should be attributed to a "Scythian affinity". Portraits found in the Noin-Ula excavations demonstrate other cultural evidences and influences, showing that Chinese and Xiongnu art have influenced each other mutually. Some of these embroidered portraits in the Noin-Ula kurgans also depict the Xiongnu with long braided hair with wide ribbons, which is seen to be identical with the Ashina clan hair-style. Well-preserved bodies in Xiongnu and pre-Xiongnu tombs in the Mongolian Republic and southern Siberia show both East Asian and West Eurasian features. Analysis of cranial remains from some sites attributed to the Xiongnu have revealed that they had dolichocephalic skulls with East Asian craniometrical features, setting them apart from neighboring populations in present-day Mongolia. Russian and Chinese anthropological and craniofacial studies show that the Xiongnu were physically very heterogenous, with six different population clusters showing different degrees of West Eurasian and East Asian physical traits. Presently, there exist four fully excavated and well documented cemeteries: Ivolga, Dyrestui, Burkhan Tolgoi, and Daodunzi. Additionally thousands of tombs have been recorded in Transbaikalia and Mongolia. The archaeologists have chosen to, for the most part, refrain from positing anything about Han-Xiongnu relations based on the material excavated. However, they were willing to mention the following: "There is no clear indication of the ethnicity of this tomb occupant, but in a similar brick-chambered tomb of the late Eastern Han period at the same cemetery, archaeologists discovered a bronze seal with the official title that the Han government bestowed upon the leader of the Xiongnu. The excavators suggested that these brick chamber tombs all belong to the Xiongnu (Qinghai 1993)."Classifications of these burial sites make distinction between two prevailing type of burials: "(1) monumental ramped terrace tombs which are often flanked by smaller "satellite" burials and (2) 'circular' or 'ring' burials." Some scholars consider this a division between "elite" graves and "commoner" graves. Other scholars, find this division too simplistic and not evocative of a true distinction because it shows "ignorance of the nature of the mortuary investments and typically luxuriant burial assemblages [and does not account for] the discovery of other lesser interments that do not qualify as either of these types." Genetics Maternal lineages A 2003 study found that 89% of Xiongnu maternal lineages are of
