Pigment vestiges on the three decorated pebbles from the excavation of Parque Darwin (Madrid), level 8470 ± 70 BP have been identified by Micro Raman Spectroscopy. Haematite and amorphous carbon were used as pigments. Microscopic contamination spots with ε-copper-phthalocyanine blue, have been detected. The analysis of the pigments used, together with their previously unknown chronology and open-air location, constitute a new point of reference for the technical and cultural uses of symbology among hunter-gatherers in southern Europe.
