Important information, particularly on organic material from graves, can be preserved due to metal compound diffusion. This allows recovery and analyses of materials such as wood, textiles, and leather.
By identifying the type of wood used, we are able to get information about man's preferences for certain woods (anthropogenic selection). The selection of a particular wood or species depends first of all on its technological properties which will guarantee the quality of the woodwork and make its manufacturing easier. Certainly, we can conclude that prehistoric peoples realized different woods and species had different qualities, and used them accordingly. However, we do not know how far the selection relied on tradition and so influenced the choice of different woods with similar technological properties.
Systematic research on wood could therefore provide valuable information about specialization and the beginning of specific trades and professional groups.
