摘要: 小长梁遗址中的旧石器以小型石器为主,打制技术相当进步,其类型与欧洲某些更晚期的旧石器有某些相似之处,而与旧石器伴生的哺乳动物化石则是泥河湾早更新世的重要成员,古地磁初步测试结果接近167万年。

Abstract: The mammalian fossils described in this paper were collected at Xiaochangliang Paleolithic site from the Nihewan Formation, which composed of fluviolacustrine variegated clay, sandy clay, silt and sand with concretions of 97 meters in thickness. They were from same level in Nihewan Formation and are referred to the following forms: Allophaiomys cf. A. pliocaenicus, Mimomys chinensis, Hyaena licenti, Martes sp., Coelondonta antiquitatis, Palaeoloxodon sp., Equus sanmeniensis, Proboscidipparion sinense, Hipparion sp., Cervus sp., Gazella sp., Bovinae indet., etc. The fossil mammals listed above are among the typical Nihewan elements and the age of the fossil-bearing beds could be considered as Early Pleistocene. The preliminary result of paleomagnetic study of Xiaochangliang Paleolithic site suggests that the absolute age of the site is about 1.67 Ma B. P. , approaching the upper boundary of Olduvai Subchron.
