内蒙古萨拉乌苏遗址的萨拉乌苏组下部原生地层于1980年出土一件人类肩胛骨化石,文中对其进行详细研究．肩胛骨所在地层的年代范围,用TL方法测定为(70．9±6．2)～(124．9±15．8)ka BP,该地层中较下部的一个层位,用碳同位素法(~(14)C)测定的年代为(35．34±2)ka BP；铀系法(~(230)Th)测定的年代为(44±7)～(63±3)kaBP；红外释光法(IRSL)测定的年代为(61～68)kaBP．在对这件人类肩胛骨化石的形态学特征进行比较研究的基础上,得出如下结论：萨拉乌苏肩胛骨多数特征与各阶段早晚期现代人比较一致,同时兼具少量尼安德特人的特征．这可能提示萨拉乌苏人类具有同尼安德特人相同或相近的上肢运动习惯．同时也可能体现了中国晚更新世人类与欧亚地区同时代及较早较晚各阶段人类之间的联系．
A primitive human scapula of the human scapula was unearthed in the lower strata of the Lower Sara Wusu Formation in the site of Sara Wusu, Inner Mongolia, in which a detailed study was carried out. The age range of the stratum where the scapula is located was (70.9 ± 6.2) ~ (124.9 ± 15.8) ka BP with the TL method. The lower one of the strata, The dating of (14) C) was (35.34 ± 2) ka BP, and the dating of (~ (230) Th) was (44 ± 7) (IRSL) dating of (61 ~ 68) kaBP. Based on a comparative study of the morphological characteristics of this scapular fossil, the following conclusions are drawn: Most features of the scapula of Salaussu are consistent with those of the early and late stages of each stage, with a small amount of Neanderthal feature. This may prompt Sara Wusu humans to have the same or similar upper extremity exercise as Neanderthals. It may also reflect the connection between the late Pleistocene humankind in China and humans in the Eurasian region and earlier and later phases.
