English: - SU 7: This layer, about 20 cm thick, is the modern upper walking surface, composed of mixed material but mainly soil and gravel, with which the quarry is paved.

- SU 8: Is the 40-to-80 cm thick travertine ceiling of the cave, hidden below the modern surface. Part of it has been removed for safety reasons during the excavation. - SU 11: This consists of a 45-to-100 cm thick highly consolidated red-brown clay soil with rare reworked volcanic products from the neighbouring Vulcano Laziale (see SU13). It also incorporated small calcareous conglomerates and clasts which are ruins of the cave. This stratigraphic unit contained abundant large mammal and small vertebrate remains, coprolites and rare lithic industries. - SU 12: Is a very compact 20-to-40 cm thick layer of reddish brown clay, containing a large number of clasts that separates the level from the above SU11 and a greater number of volcanic products. Abundant small vertebrates and few lithic industries were present, while large faunal remains and coprolites were absent. - SU 13: A homogeneous greyish green layer of high-ly consolidated volcanic tephra and pyroclastic products. This sterile layer attests to the eruptive phase of the Vulcano Laziale complex dating at 70±2 ka. - SU 14: Consists of a 50-to-100 cm thick very solid reddish paleosol. The presence of light patina of manganese is widespread, perhaps being evidence of a recurrent presence of water. Extremely rare lith-ic and bone remains were also found.

- SU 15: This bottom layer is made of calcareous en-crustation and travertine with a strong presence of manganese patinas. It represents the natural floor of the cave.
