This campaign continued excavations in area B, opened in 2010, and in two new areas (C and D), situated a few metres to the south.

The palaeontological excavations covered a front of about 12 m to a maximum height of circa 4 m.
The most important work took place in areas A and C. Initially, the various layers to be numbered were identified in area A (which continued that of 2010). Following evaluation, layer 0 in area C was identified. The position of the layers present in area C is: direction of dip 214° – slope 7°.
In area A, numerous layers were identified and exposed, distinguished by lithological variations and fossil content. These are described below, from bottom to top, linking back to the description given for the 2010 excavations:

Layer 1 – Massive fossil-bearing nodular limestone, yellowish-white in colour. Thickness 48.0 cm;

Layer 0 – Yellowish marl with abundant nummulites, bivalves and gastropods. Average thickness 15.0 cm;

Layer -1 – Whitish massive limestone, containing foraminifers, echinoderm spines and small gastropods. Thickness 26.0 cm;

Layer -2 – Yellowish marly interbedded layer. Thickness varying between 8.0 and 3.0 cm, on average 3.0 cm;

Layer -3 – Massive limestone, similar to layer -1, containing foraminifers, small bivalves and abundant bioclasts (fragments). Thickness 8.0 cm;

Layer -4 – Yellowish marl. Thickness 4.0 cm;

Layer -5 – Brownish massive limestone containing macro-foraminifers and small bivalves. Thickness 11.0 cm;

Layer -6 – Yellowish marl. Thickness 2.0 cm;

Layer -7 – Massive limestone, varying in colour from yellow to grayish containing abundant macro-foraminifers, bivalves, gastropods and small sporadic ill-preserved corals. Thickness 25.0 cm. Presence of bioturbation (in lesser number than those in layer -8). The layer contains more fossils than layer -8. At the transition between -7 and -8 localized, discontinuous presence of bioturbation in yellowish marls which increased significantly towards the upper part;

Layer -8 – Yellowish massive limestone. Thickness 14.o0 cm. Presence of foraminifers, gastropods, small sporadic corals, abundant bioclasts and abundant bioturbation;

Layer -9 – Yellowish marls. Thickness 10.0 cm. Discontinuous layer;

Layer -10 – Calcarenite with a few bioclasts and bioturbation. Thickness 11.0 cm;

Layer -11 – Yellowish arenite, not very compact. Maximum thickness 10.0cm.

In area C, a small test pit was dug (13.0 × 65.0 × 11.50 cm) in order to undertake a palaeo-ecological investigation using the volume method, to check the density of faunal remains present. The excavated material was crushed in order to recover most of the palaeontological content. The crushed rock was placed in two buckets filled with water and then passed through a series of sieves for granulometric analyses. The results of this analysis and that undertaken on area A, layer 4, are being processed.
Rock samples were taken from the various layers. A preliminary analysis of the faunal content showed that almost all finds were molluscs or foraminifers. Subsequently, a number of shark teeth, vegetal remains, echinoderms, crustaceans etc were recovered. Overall, 480 palaeontological finds were recovered from the excavation at Monte Duello.
