Truncated-faceted pieces from lower layers by industry of Obi-Rakhmat grotto (Uzbekistan)

There are truncated-faceted pieces from lowers layers (19–21) of Paleolithic site Obi-Rakhmat (Uzbekistan) being examined in this article. These layers contain the majority of truncated-faceted pieces. In general, the truncated-faceted pieces are flakes that exhibit a truncation on one or several margins, which serve as a platform for the removal of one or more small flakes. In transitional industry of Obi-Rakhmat Grotto this technology is often occurs, but we suggest the truncated-faceted tools to be of the most interest, because they allow to observe cultural and chronological connections between different regions. Main morphological elements of these tools are truncated-faceted platform, flake scars removed from this platform and retouch on edges. Considering the features of these elements there can be singled out three typological groups of truncated-faceted tools. Typological classification is followed by technological scheme which allows to show the variability of the given tools. There are three main points of view on the functional aim of truncated-faceted pieces, but in this article we consider them as specific tools. According to its possible functional purpose («sinew frayers»), they may well correlate with the characteristic faunal assemblage grotto Obi-Rakhmat, which is dominated by the limb bones of animals.
