Prehistoric research, in the dawn of the third millennium, faces contradictory challenges. While scientific advances and technological resources allow for new analytical procedures, with relevant new knowledge being produced and conveyed, institutional and financial resources for research are growingly put into question, and in several countries contextual instability prevents any field or laboratory research to pursue. In this context, scholars face the need to strengthen their research networks across countries and continents, attempting that no constraints, beyond the needs of research, condition their participation in investigation programmes, meetings or congresses.
