In this paper we present advances in the research on engraving production techniques used at Piedra Museo archaeological locality, in Santa Cruz, Argentina. The outcrop on which the original engravings were documented resulted from a Tertiary marine transgression-coquinoid base-that is extremely friable, which could have influenced the decision to create these motifs. The goals of this paper are to describe the engraving techniques used at this archaeological site by carrying out experimental engraving and examining the traces left on the stone tools used for those experiments. The results allow us to identify the origin and development of micro - wear on the artefacts used, which is consistent with that observed by other researchers, with some particular differences. Both functional analysis and analysis of the “chaîne - opératoire” involved in petroglyph production are considered fundamental stages in the formulation of hypotheses about ancient hunter - gatherer societies.
