东梁峁遗址是山西吉县清水河流域的一处旧石器时代早期遗址。该遗址于2009~2010年发掘,发掘厚度约10~16m,揭露面积约1000m²,出土石制品22件,动物化石2682件。石制品以石英岩、燧石和石英砾石为原料,硬锤直接打击法进行剥片和石器加工,石制品类型有石片、断块和石器,其中石器类型为小型石片石器,包括刮削器和尖状器。动物化石数量多,可鉴定化石种属包括梅氏犀、马、牛、肿骨鹿、野猪、鼠兔、鼢鼠和一些小型食肉类动物,是中国北方中更新世的常见种属,反映了疏林草原的生态环境。黄土地层和动物群对比分析显示,该遗址形成于中更新世早期阶段。该遗址的发现为研究中国北方旧石器时代早期的文化面貌及其分布状况提供了重要资料。

The Dongliangmao Lower Paleolithic Site(36°02.873′ N、110°34.069′ E, 706ASL) is located along the Qingshuihe River in Jixian County, Shanxi Province, North China. This site was excavated from 2009 to 2010. The excavations exposed a section of some 15m depth and an area of about 1000m². Totally 22 stone artifacts and 2682 animal fossils were unearthed. The stone assemblage includes flakes, chunks and retouched tools, which were made of quartzite, flint and quartz collected from the near Yellow River by ancient human. The tools were chipped and retouched into small-sized scrapers and points by direct hammer percussion. The animal fossils can be identified as Dicerorhinus merki Jäger, Equus sp., Bovinae, Megaloceros pachyosteus Young, Sus sp., Ochotono sp., Myospalax fontanieri and Carnivora et al., which were the common species in North China in the Early Middle Pleistocene, indicating the environmental background of open forest steppe. All the artifacts are unearthed from the lower Lishi loess with 12m thick loess-paleosol sequence, and its gravel bed. Geomorphological and biostratigraphic comparison shows that the age of this site should be Early Middle Pleistocene. The Dongliangmao site provides an important information for the studies on the early Paleolithic archaeological culture and its distribution in North China.
