The Xiaohe 'Little River' Tomb complex refers to a bronze-age burial site located near Lop Nur, in the Xinjiang Uygur Autonomous Region of western China. It is an oblong sand dune, from which more than 30 well-preserved mummies, buried in air-tight ox-hide bags, have been excavated. The mummies, the earliest of which date from around 4000 years ago, appear Caucasoid. Genetic analysis, however, revealed an admixture of population from the East and West, with the paternal lineage exclusively west Eurasian, and the maternal lineage a mixture of east and west Eurasian. The entire Xiaohe Tomb complex contains about 330 tombs, about 160 of which have been looted by grave robbers. The Xiaohe remains contains the largest number of mummies found at any single site in the world to date.
