关于小长梁石制品的进步性

小长梁遗址发现于１９７８年。尤玉醉等研究后认为其时代属于早更新世。石品被一些学者认为相当进行，甚至已经达到黄土时期的式样。于是出现了年代古老和石制品进步的矛盾。笔者检查和分析了小长梁发现的石制品，认为细小的不规范的石制品并不说明技术的进步；小长梁石制品的原料利用率并不高；几件不规则的石叶状的石片也不足以说明打片技术的进步；所谓修理台面的石片亦难于肯定；至于所谓极精细的加工迹似乎用使用痕迹来解释更为

ON THE PROGRESSIVENESS OF THE STONE ARTIFACTS FROM THE XIAOCHANGLIANG SITE AT YANGYUAN, HEBEI

The site of Xiaochangliang is situated at Datianwa, Yangyuan County, Hebei Province. It was found in 1978. You Yuzhu et al . suggest that the site belong to early Pleistocene in age. More than one thousand pieces of stone artifacts were found in situ in association with a mammalian fauna including Mimomys chinensis,Hyaena licenti, Equus sanmeniensis and Proboscidipparion sinense . Some scholars regard the stone artifacts show rather progressiveness, even achieve the pattern of the loess period. Therefore occurs contradiction between the early age and the progressive techno\|typology of the stone artifacts. The present author reexamines and analyses the stone artifacts from the Xiaochangliang site. In his opinion, the irregular small artifacts do not mean the progressiveness of technology. According to You Yuzhu et al . in the collections from Xiaochangliang the rate of waste attains a percentage of over 90%. It means the rate of utilization of the raw materials is low rather than high as some scholars maintained. A few blade\|like flakes with irregular sides are far from evidence of progressive technology. The so\|called prepared platform on a flake has 4 facets due to the blows of different time even from different directions. It is difficult to affirm this flake has a prepared platform. Two flakes have been described as tools with very fine retouches. The present author thinks they are utilized flakes. In short, judged from flaking and retouch of the stone artifacts, the Xiaochangliang collections show simple and rough working, no any distinct progressive character can be observed on them. The types of stone tools are few and simple rather than complex. In comparison with those from the Peking Man site, the stone artifacts from the Xiaochangliang site are less progressive than the former; the latter does not attain the techno\|typological level of the late Pleistocene ones. It seems to the author that based on the materials so far published, the character shown on the stone artifacts from the Xiaochangliang site, by and large, coincide with the conclusions offered by the biostratigraphy and paleomagnetism.
