Bipolar knapping in Gravettian occupations at El Palomar Rockshelter (Yeste, Southeastern Spain)

摘要

This paper examines the stratigraphic sequence of El Palomar Rockshelter, paying special attention to the levels associated with the Gravettian. The preliminary techno-typological study of the lithic collections of these Early Upper Paleolithic levels reveals a large number of splintered pieces that have previously been linked to two different activities-bipolar fl intknapping and the use of intermediate tools (wedges) for working hard materials such as bone, wood, and antler. An experiment was carried out to determine the different characteristics resulting from each process, with special emphasis on macroscopic traces. All the main bipolar knapping features identified in this experimental program were also present in the splintered pieces from El Palomar, thus providing proof that the use of the bipolar knapping method was routine during this period. The implications of the use of this knapping method in El Palomar are also discussed.
