The excavations of the paleolithic layer in the locality of Fontana Ranuccio aimed to determine the extension of the fossiliferous level.

It was very slightly sloped in a north/west-south/east direction which indicates the probable existence of a drainage system, set up in a similar way to the existing one. The highest concentration of finds was in the northern part of the area.

These included bones, teeth, macro-remains of fossilised wood, deer antlers, implements attached to bone and fragments of worked flint. Of particular interest for their very good state of preservation and completeness are the Elephas half mandible and adjacent deer antler, the Elephas molar and several bone implements chipped on the distal part, the ribs of a pachyderm and the distal extremity of a bifacial implement of dark flint.
