Asturian culture
The Asturian culture is an Epipalaeolithic or Mesolithic archaeological culture identified by a single form of artefact: the Asturian pick-axe, and found only in coastal locations of Iberia, especially in Eastern Asturias and Western Cantabria. It is believed that the Asturian tool was used for seafood gathering, and the sites where they are found are associated with very large shell-middens (concheros in Spanish), which can fill caves to the ceiling.
