This was the seventh campaign of excavations on the site of Monte Duello. The work concentrated on a front c. 4 m wide with a maximum height of c. 1.5 m in correspondence with ‘scavo A’. In addition, a small trench was opened in the area of the rocky outcrop containing sponge fossils (‘scavo E’).

Prior to the start of the excavations cleaning was undertaken in the area of ‘scavo A’, with the removal of soil and other surface detritus present on the rock face in addition to the partial removal of the detritus previously left to cover the fossil-bearing layers. A small mechanical digger was used to remove the detritus and a trench was opened to link ‘scavo A’ with the trench positioned downhill.

The excavations intercepted a layer with volcaniclastic rocks. It was established that the calcareous layers above rested directly on altered volcanic rocks that are greenish in colour with light-brown and yellowish variegation. This is probably a non-stratigraphic contact, suggesting that the limestones slipped onto the volcanic rocks. This allowed a sub-horizontal shift of the limestone rock mass, which fractured parallely at the face. The preliminary analysis of the palaentological material made it clear that almost all of the finds were Molluscs (gastropods and bivalves) and Foraminifers (_Nummulites_ brongniarti). Fish and echidna teeth were also found. Rock samples were taken for study.
