泥河湾盆地板井子遗址锯齿刃器实验研究

锯齿刃器是中国旧石器时代存在的一种重要器物类型,然而,其模糊的类型学鉴定标准使得该器物的研究在国内学术界没有得到足够的重视。板井子遗址是河北泥河湾盆地晚更新世早期的一处重要旧石器遗址,出土较多锯齿刃器。本文通过实验研究,证明板井子遗址的锯齿刃器齿凹的大小与石锤修理部位面积大小呈正相关关系,且遗址中有一部分锯齿刃器是用修理部位面积较小的带尖石锤打制而成,并在遗址标本中找出尖端有散漫坑疤的带尖石锤。本文复原了锯齿刃器的制作工艺流程,证明锯齿刃器是一个稳定的加工过程,需要特殊的石锤来加工,并对其功能进行讨论。

A replication study of denticulates from the Banjingzi site,Nihewan Basin

The denticulate is one of the most important retouched tool types for the Paleolithic in China. However, the relatively indeterminate classification of the category results in the denticulate receiving less attention in Paleolithic research. Banjingzi site is an important early Late Pleistocene Paleolithic site in the Nihewan basin, North China. The large number of excavated denticulates (accounting for 9% of the retouched tools) makes the site most peculiar in the Paleolithic of the Nihewan basin, and even in north China. Denticulates, are known at the Donggutuo site in the Nihewan since the Early Pleistocene. Those excavated from the Banjingzi site may imply some special adaptive behaviors adopted here by early hominins during early Late Pleistocene. Through stone artifact replication, the authors consider that there are at least two retouch techniques to create denticulates, one using a small pebble hammerstone and a second using a pointed hammerstone. The pointed hammerstone modification technique, however, is the main retouching technique for denticulate fabrication in the Banjingzi site. Another approach of our replication study is to reconstruct the processes of denticulate manufacture, which has shown that it is a relatively stable fabrication procedure. As a result, the current study should bring attention to the denticulate in Paleolithic research in China. Finally, we also combine sample observation with the experimental replications for this current paper.
