Among the sites of fossil finds, the most famous is surely the Pessàra found in the Zovo district in the outskirts of Bolca. It is a hollow tunnel in which tens of thousands fossils of fish, plants and remains of invertebrates they were brought to light in an extraordinary state of preservation. For walkers, the Pessàra is easily accessible through the "paleontological walk" from the center of Bolca down to the cave allows you to discover the various geological phenomena.
To continue the itinerary and discover another extraordinary heritage you have to go as far as Roncà, a small village at the foot of Monte Calvarina. Here is the new Museum of Paleontology that offers a broad picture of the fauna and flora of the Lessinia from over 40 million years ago. The fossils on display, from the local deposit of Val Nera, the current Valle delle Chiese, today are the result of more than 200 years of study and research. The most outstanding finds were the skeleton and the reconstruction of a huge Prototherium, an animal of the Siren family, marine mammals of medium-large size.
