A journey backwards in time. Until the Cretaceous, 110 million years ago, when on the slope of the Matese, where Pietraroja rises, the lagoon was expanded.

At that time, animals fossils were populating that natural habitat: the protagonists of the multimedia museum of geology and paleontology, well-known for the fossil of the baby dinausor of the Scipionyx samniticus specie, nicknamed Ciro, which is the major attraction.  The other rooms of the museum which illustrate the geological evolution of the Peninsula until the actual shape are not to be excluded.
