Petroglyph Manufacture by Indirect Percussion: The Potential Occurrence of Tools and Debitage in Datable Context

Petroglyph manufacture probably often involved indirect percussion, especially for carefully made lines and edges of larger figures. Experimental replication shows that during indirect percussion, debitage is produced from the chisel-stone that should be recoverable in archaeological context at rock art sites. Following experiments that demonstrated how the debitage is produced, this report describes its characteristic shape and provides suggestions as to what sorts of contexts might contain this evidence
