Wear-use traces in lithic tools
The carved flint, worked bones and those of animals found in the archaeological sites are remnants of the activities carried out by groups of people in the past.
The study of the traces of use or traceology, may be inferred by microscopic analysis of wear, chips, polished or stretch marks, the material that came in contact flint instruments and movement they made. Thus it is possible to know that the material was frequently worked wood and that work on the flesh or skin is present in a much smaller proportion. Different studies conducted in European Upper Paleolithic sites have shown that the scrapers are identified mainly with the work of scraping the skin, while the chisels and drills were used for grooving on wood or bone.
Identifying the function of allowing lithic technical know not only but also by the location of the useful space, specific activity areas. The determination of the activities we approach the function of the site, its relationship with other settlements and all that generates knowledge about prehistoric groups.
