Ivory objects from the chalcolithic fortification of Leceia (Oeiras)

Resumen

Ivory constitutes a new introduced material, an innovation, whose starting point on the Iberian Peninsula coincides with the beginning of the Chalcolithic (around 3000 BC). As an exotic and in the Metal Ages on the Iberian Peninsula no more locally available material, it was from the beginning of archaeological investigation of special interest. So it was supposed to give clear hints on prehistoric contacts and exchange by sea.
