The shape is almost squared with a circular hole in the middle (int. diam. 3.9). The surface is very calcareous. The object is thinner towards the extremities. P2 ZSB 105.16 q 163.2 df gr lg 8.7 w2 8 th 2.5 ds small fragment of quite thin basalt grinding stone. The upper face is flat. The shape is irregular. Towards the edge the shape is quite concave. P2 ZSB 105.16 q 112.3 df gr lg 11.2 w2 8.5 th 2.9 ds small fragment of quite thin basalt grinding stone. The upper face is flat. The shape is irregular. Towards the edge the shape is quite concave. P2 ZSB 105.16 q 150.1 df chipped stone ct laf lg 2 w2 1.3 th 0.4 ds small fragment of obsidian core. Bulb percussion and irregular edges. Working traces on all the surface. P2 ZSB 16.34 q 151.1 df flake ct laf lg 2.3 w2 1.6 th 0.8 ds small fragment of obsidian with irregular shape. Working traces above all the core. P2 ZSB 16.34 q 109.1 df gr lg 6.6 w2 3.8 th 3.5 ds small fragment of basalt with irregular shape and surface. It could belong to a grinding stone P1 discarded q 112.4 df gr lg 7.2 w2 5.3 th 6.2 ds fragment of basalt grinding stone. The upper side is completely flat, the lateral side (just one is preserved) is obliqual. Calcareous encrustations on the surface. P2 ZSB 105.16 q 112.5 ;df laf lg 10.3 w2 7.5 th 3.9 ds lithic artifact with almost triangular shape. Since all the surface is very encrusted, one of the sides seem quite flat and smoothed, the other quite porous. It's impossible to argue the function of the object. P2 ZSB 105.16 q 112.2 df gr lg 16 w2 9 th 7.5 ds fragment of basalt grinding stone with irregular shape. All the sides are very encrusted. From the material we can assume that the fragment belongs to a grinding stone. P2 ZSB 105.16 q 106.3 df la lg 17 w2 11.4 th 6 ds lithic artifact with almost rectangular shape. The material could be basalt also if it seems characterized by a different specific weight. A calcareous layer covers all the surface. P2 ZSB 105.16
