During the excavation in the area of Tomb IV at the Neolithic necropolis at S’Elighe Entosu several pottery fragments were recovered belonging to a vase externally decorated with a previously unknown triangular motif. The shape of the vase and the decorative motif recall Sardinian pottery production of the Middle Bronze Age 2. However, the position of the motif together with the method of realisation (possibly through the application of different coloured slips) is unique in the panorama of the Sardinian Middle Bronze Age.
