Abstract

During the 1960s, fossil beds characterized by a tropical-sea malacofauna were discovered by G. Ruggieri and G. Buccheri in the Island of Ustica, on the southern slope of Falconiera hill, 32 m asl. Thanks to the presence of Strombus bubonius and other Senegalese guests, the authors estimated that the molluscan fauna had lived around 125,000 years ago, during the Tyrrhenian stage. Recently on the initiative of the “Centro Studi e Documentazione Isola di Ustica”, a research has been initiated to verify the persistence of sand-layers mixed up with Tyrrhenian fossils, even though, in the last 50 years, that area has undergone great changes, because of earthworks which have sealed the deposit. The new research led to the discovery of a fossil assemblage formed by 22 taxa (16 species of gastropods and 6 of bivalves), characterized by the presence of some Senegalese guests and other accompanying species that can be associated with the Eutyrrhenian subunit (MIS 5.5). This is the main subject of this note, along with the suggestion to preserve what remains of the Ustica Tyrrhenian deposit.
