The bottom 10 meters of the site contain artifacts from the Middle Paleolithic, and are capped by a volcanic ash (the Campanian-Ignimbrite eruption in Italy) which was deposited 40,000 years ago. Therefore, we know that the bottom 10 meters are all older than 40,000 years old. The deepest layers of the site, according to geological evidence, may reach as far back as 130,000 years old, but this needs to be verified.

Above the Campanian-Ignimbrite volcanic ash, the artifacts and radiocarbon dates indicate that the site was occupied from about 25,000 years ago (during a period in the Upper Paleolithic known as the Gravettian) until the Bronze Age. There is evidence of occupation during the late Upper Paleolithic, the Mesolithic, Neolithic, and Bronze Ages.
