摘要：Polished stone tools play a very important part in the process of restoring the economic and daily life aspects of the prehistoric communities. Their structure and development stage suggest both the technological level and the creative ability of the prehistoric communities in using certain types of raw materials ( CUCO., MURARU , 1985, 605) and also the interactions between them and the ecosystem. On the other hand, they can reveal the economic differences between contemporaneous settlements, but also between cultural phenomena on different chronological scales ( CUCO., MURARU , 1985, 605) pointing out the dynamics of the economic processes specific to a period or culture. Until recently, the polished stone tools were dealt with in a distinct chapter of a monography that only confined to material description and typologies. Nowadays, the Romanian archaeologists take more interest in studying the lithic tools and attempt to surpass the descriptive stage and the futile inventories through interdisciplinary studies. Thus, new information regarding stone tools manufacturing, raw materials and their source area entered the scientific circuit. The new born theories deal with the prehistoric communities economy, but also with the intercommunitary contacts as a means to spread goods, ideas and innovations.
