Lo Scavo della Tomba X nella necropoli ipogeica di Santu Pedru (Alghero - Sassari): unadomus de janasdelle prime fasi del Neolitico Recente

This paper reports the results of excavation in the Tenth Tomb of Santu Pedru necropolis: a typical rock-cut grave of Sardinian Neolithic age (the so-called ”domus de janas”). Since 1959 researches carried out in this site by E. Contu and A. Moravetti discovered several important hypogeal tombs (i.e. the First Tomb, well known as ”Tomb of the Tetrapod Vases”) with rich cultural remains belonging to the following cultures: Ozieri, Filigosa, Abealzu, Monte Claro, Campaniforme (Beaker), Bonnanaro and Nuragic. Tomb X was discovered by chance in autumn 2004, during widening works of state road 127bis, and explored in summer 2005. The grave is composed by long corridor (dromos) and five rock-cut rooms: the main cell have two pillars, an hearth sculpted on the ground and a ”false-door” carved on the front side. Materials found in this tomb are very interesting: inside the hypogeal rooms were discovered remains of the latest burials of Ancient Bronze Age (Bonnanaro culture) and some pottery fragments of former Copper Age burials (Filigosa and Monte Claro cultures). Remains of the first burials were found outside in the corridor (dromos) area: it concerns mainly pottery fragments of the Middle-Late Neolithic phase named ”San Ciriaco culture”. Apart from the controversial case of the tomb of Sant'Iroxi-Decimoputzu, this is the first time the ”San Ciriaco” evidences are found in a rock-cut tomb of domus de janas type, wich were considered exclusive of the following Ozieri culture.
