The Paleontology Museum of Naples is the most recent of the four affiliated with the Center for Natural and Physical Science Museums of the University Federico II. It was established in 1932, although fossil collections were already housed in the Royal Mineralogical Museum of Naples before this date, in the nineteenth century. Today, it is located in the Cloister of Saints Marcellinus and Festus. It displays various collections: fossil fish from Giffoni Vallepiana, Pietraroia, and Castellammare di Stabia, mammals (such as a skull of a young Elephas antiquus italicus), a fossil palm, marine reptiles, and flying reptiles. Since 1996, there has been a very well-preserved fossil specimen of Allosaurus fragilis from North America.
