-Have you ever imagined that Picentini mountains, over a hundred million years ago, had a lagoon? REMINGTON

Fossils of high scientific value and historical-cultural give clear guidance on the geology of a region. Be mentioned those of the fossil fish from the three fields ittiolitiferi of Campania. These, arising largely from the studies and research carried out since the last century include: the fish of the Middle Triassic of Giffoni Vallepiana (SA) dating back some 210 million years ago, those of the Cretaceous Pietraroia (SNL) and Castellammare di Stabia (NA) of about 115 million years. The fossil deposits of Giffoni Vallepiana, located in the chain of mountains running from the Apennines to the Sorrento peninsula, has been under study since 1797, when work began, wanted by the government for a possible use of fossil fuels in the area. That was the year Andrew Savarese, on behalf of the government, visited the Monte Pettine to verify the extent and the possible exploitation of the field. In 1809, Pomegranate was interested in the area and a few years later, in 1815, Giovanni De dug two tunnels, one of which reached 16 meters deep. All of these studies, however, did not lead to any important result. In 1820 Matteo Tondi on behalf of the Academy of Sciences of Naples, studied samples of minerals and concluded that they did not offer any advantage industry. It was only in 1854 that was made the first analysis of bituminous and lignite levels present in some success led the government to entrust Oronzio Gabriele Costa detailed study of the area. In 1858 were intensified research in the area, coordinated by Costa, and were carried out explorations and excavations for the industrial exploitation dell'ittiolo shale content (hence the name "ittiolitici shale"). After nearly two years the research was abandoned and the Government of Costa exhibited the results for the industrial part and published those relating to geological and paleontological observations. Despite the negative results of this research for industrial purposes, they were of great scientific importance because it brought to light a large number of fossilized fish in the levels bituminous. The first reports of specimens of fish fossils Giffoni date back to 1815, when the knight Filippo Basso took a few specimens in honor of King Ferdinand I. Following Costa recovered from the area the largest number of specimens, mostly fish but also molluscs and plants, which are currently part of the prestigious collection housed at the Museo di Giffoni. The specimens were subjected to various Giffoni character paleontological work and the results published by Costa 1848 and 1866. The consistency of the current collection amounts to about 100 copies.
