In the Ekain cave (Deba, Gipuzkoa), a small group of parietal art representations have been found, executed by engraving on clay. The similarities between these and the well-known paintings of horses point to the same chronology: Upper Magdalenian, approximately 15,000 years ago. This type of figurative engravings traced with the finger is not very common, but they appear in the Iberian Peninsula and the south of France throughout the Upper Palaeolithic. In this talk we present the new findings and the implications of the use of this technique in the framework of Palaeolithic Art research.
