乌兰木伦遗址由邻近的第1、第2和第3地点组成。其中在第1地点获得了石制品2780件、动物化石3423件,并发现用火遗迹。遗址年代为距今7～3万年,属旧石器时代中期。遗址为原地埋藏,其石制品类型及工业组合与欧洲旧石器时代中期文化近似,动物化石则属于华北晚更新世的萨拉乌苏动物群。

The Ulan Moron Site located in Ordos City, Inner Mongolia consists of Loc. 1, Loc. 2 and Loc. 3. In Loc. 1, totally 2780 stone artifacts and 3423 mammalian fossils were obtained together with fire-use remains by a rescue excavation in 2010 and a formal excavation in 2011. Dating result for Loc. 1 from ^14C and OSL methods is 70 - 30 ka BP, meaning that this site belongs to middle Paleolithic Age. A primary study shows that the site was deposited in situ. The characteristics of lithic assemblage are quite similar to the middle Paleolithic cultures in Europe. The mammalian fauna are the part of Sjara-osso fauna of the late Pleistocene Epoch in North China. Large amounts of bone artifacts and fragmentary bones including those with obvious cutting marks indicates their close relationship with hu- man behavior. In a trench of Loc. 2 one trace of rhinoceros footprint was discovered in addition to some stone artifacts and fossils. The Ulan Moron Site is an important discovery of middle Paleolithic Age in China. All these evidences provide good materials for the comparative study of human behavioral adap- tation and modern human origin.
