At the end of August 2011, a continuous core sample was taken in the rock at the edge of the paleontological excavation in order to check the actual thickness of the Pesciara deposit and for the presence of other laminated and non-laminated layers, rich in paleontological material. The most suitable point for the sampling corresponded with the entrance to the so-called “Cava bassa”, one of the two galleries closed to the public, situated at the base of the rock face delimiting the north-eastern side of the Pesciara.

In order to make the core sample as perpendicular as possible to the stratification it was necessary to make a perforation at an angle of about 60°. The resulting log showed the presence of a pack of fossil-bearing volcanoclastic rocks, at least 17.50 m thick and provided a large amount of information (geological, stratigraphic, sedimentological etc.) which will significantly increase the modest level of present knowledge.

The core-sample also excluded the existence, at least in the northern part of the Pesciara, of carbonate rocks in a stratigraphic sequence with the outcropping rocks of the Pesciara.

Excavations took place between the 3rd-24th October on the historic site of the Pesciara di Bolca (Verona).

Before excavation began, the rock faces present along the entrance to the gallery opened in 2004 were surveyed. Lastly, an accurate barring was undertaken in correspondence with the rock face above the entrance, in order to check the state of the pelmet and fissure meters.

The stratigraphy examined was the same as that seen and described in previous years. No particular differences were noted with respect to what was documented before, so the description of the layers can be taken from the previous report.

Excavation took place mainly in the south-western part of the gallery, in particular along its front. Agricultural work and the opening of the laminated limestones led to the recovery of 116 finds belonging to various species. Plant remains, for example beautiful individual leaves, were also found. A good number of fish remains, including a swordfish (Blochius?) and an anguilliform fish, were recovered.
