ABSTRACT

The presence of pseudo artifacts in the archaeological record is not rare, especially in contexts where lithic raw material of good flaking quality is naturally available. If taphonomic processes and lithic raw material are in place, assessing the contribution of pseudo artifacts is a necessary step in a taphonomically oriented archaeological research design. This was the case at Casa de Piedra de Rosello 1 rockshelter (Chubut, Argentina), where chert from the bedrock is the dominant toolstone throughout the archaeological sequence. Research conducted at the site included in situ rockfall experiments, clast sampling, and techno-morphological analysis of both experimental and collected flaked specimens. It is concluded that although conditions for rockfall pseudo artifact production exist at CP1, its contribution to the overall lithic assemblage was negligible. Nevertheless, the impact of pseudomorphs on archaeological interpretations would be more important in stratigraphic units exhibiting low discard rate or no artifacts at all.

摘要

考古记录中伪造文物的存在并不少见，尤其是在天然存在优质剥落质量的石质原料的情况下。如果埋葬过程和石质原材料到位，评估伪人工制品的贡献是面向埋葬学的考古研究设计的必要步骤。Casa de Piedra de Rosello 1 rockshelter（阿根廷丘布特）就是这种情况，基岩中的燧石是整个考古序列中的主要工具石。在现场进行的研究包括现场落石实验、碎屑取样以及实验和收集的片状标本的技术形态分析。得出的结论是，虽然 CP1 存在落石伪造物生产条件，它对整体石器组合的贡献微乎其微。然而，假晶对考古解释的影响在表现出低丢弃率或根本没有人工制品的地层单元中更为重要。
