The excavation area lies on the south-western slope of Monte Duello, in via Casarotti, Montecchia di Crosara, at about 109 m a.s.l.

This season’s excavations aimed to trace the important Bartonian (middle-upper Eocene period) deposit of molluscs and marine mammals, known since the end of the 18th century, and to correlate the stratigraphic data from preceding excavations.

The excavations took place along a front that was ca. 6m wide overall and a maximum of ca. 1.5 m high in correspondence with Excavation A and a linking trench was dug between Excavation A and Excavations D and E. The actual paleontological excavations were carried out in correspondence with excavation area A, while about twenty samples of marl sediments were collected from the link trench and all the fossils that came to light during the digging of this trench were recovered.

Before the paleontological excavation, the various outcropping layers in Area A were identified and marked according to the numbering system used in previous years. The work mainly involved layers 1, 2, 3 and 4. Numerous gastropods and bivalves were found within this stratigraphic sequence.
The excavations in “D” and “E” produced a modest number of well-preserved echidna remains.

Rock samples were taken from the various layers. A preliminary analysis of the paleontological remains showed that almost all the finds were molluscs (gastropods and bivalves) and Foraminifers (Nummulites brongniarti).
All of the fossils are housed in the storeroom of the Roncà Paleolontological Museum.
During 2013, the study continued of the sponge spicules found in Excavation C at Monte Duello during the 2011 and 2012 campaigns.
