The excavation started on the 7th October 2011.

Initially, work continued on the removal of the layers on the front opened in 2010. Unfortunately, after several days work, removing potential fossil-bearing layers, which produced no new finds, the underlying layers were reached. These were made up of compact non-fissile limestones.
This trench was abandoned and back-filled. It was decided to open a new trench a few metres south of the area excavated between 1996 and 2010. The surface material of soil and rock fragments were removed in order to reach the underlying laminated layers.

The partial removal of the first potentially fossil-bearing layers (Po1, Po2 and Po 3) began. So far they have only produced a few fragmentary remains of fish fossils and disarticulated and isolated skeletal elements – also of fish. The surface layers varied in colour between grey and light brown and were slightly undulated with vertically fractures.

The upper part of layer Po1 mainly contained incomplete and disarticulated fossils and a few complete examples, covered by crystals and calcite. These were mostly the fragmentary remains of indeterminate teleostei fishes and pycnodontes, including two isolated scales (one large) and a vegetal specimen. There was a notable absence in these first layers of the Rhyncodercetis and small Beryciformes that were always present in layers excavated in previous years.
