乌兰木伦遗址于2010年发现并进行了首期试掘,在7个文化层位中获得石制品1500余件、动物化石千余件以及人类用火遗迹。初步观察和研究表明,该遗址以石片石器为特点的石制品类型十分丰富,工具组合具有明显的旧石器中期的特点,且与欧洲的莫斯特文化存在不少相似之处;以披毛犀为代表的哺乳动物化石属于华北晚更新世萨拉乌苏动物群;沉积相和哺乳动物、软体动物化石的性质表明当时人类生活于较为温暖、湿润的气候环境中;化石总体比较破碎,一些碎骨化石上可见明显的石器切割痕迹,同时发现有大量骨片,带剥片痕的骨核化石和若干骨器标本以及烧骨,反映出当时人类的肉食、熟食习惯等利用动物骨骼的生活行为方式。经~(14)C与光释光结合测定乌兰木伦遗址年代为距今70～30ka,属于旧石器时代中期。乌兰木伦遗址的发现、试掘与初步研究,为我国北方旧石器中期文化的研究增添了新的内涵,同时也为现代人起源和中西方文化交流研究提供了新的线索。
In 2010, Wulan Mulun Site was discovered and conducted the first trial excavation. It obtained over 1,500 pieces of stone products, over 1,000 pieces of animal fossils and human remains of fire in seven cultural levels. Preliminary observations and studies have shown that the site is characterized by stone tablet stone artifacts is very rich in type, the tool combination has obvious Mid-Paleolithic characteristics, and with the European Moste culture there are many similarities; with coat The mammalian fossils, represented by rhinoceros, belong to the Late Sinhala fauna in northern China. The sedimentary facies and mammals, the mollusc fossils, indicate that human beings were living in warmer and humid climates at that time. The fossils were generally fragmented and some Bone fossil visible traces of stone cutting, but also found a large number of bone fragments, with stripping marks of bone fossil bone and some bone specimens and bone burning, reflecting the human meat, cooked habits such as the use of animal bones life behavior the way. By ~ (14) C combined with light-emitting light determination Wulan Mulun site for dating 70 ~ 30ka, belonging to the mid-Paleolithic. The discoveries, trial excavations and preliminary studies of the Wulan Mulun Site add new meaning to the study of the medium-term Paleolithic culture in northern China, and provide new clues for the origin of modern people and the study of Sino-Western cultural exchanges.
