    Paleontologic and stratigraphic data from Quaternary deposits of Leghorn subsoil (Italy)

    ABSTRACT
    The Authors describe two malacofauna fossils attributable, on biostratigraphic and stratigraphic base, to Pleistocene and Late Pleistocene, observed by a drilling carried out in the east of the city of Leghorn, Italy. The malacological fossil association of Pleistocene was low in number of individuals but well characterized in the number of species; the one attributable to the Upper Pleistocene is related to contemporary associations already known in literature for Leghorn subsoil, and shows two species not previously reported. The malacofauna of the Lower Pleistocene is characteristic of the current coastal muddy debris; Tyrrhenian malacofauna mainly consists of allochthonous elements, from a “Posidonia meadows” and the depositional environment is attributable to the Mediterranean current seabeds. The stratigraphy of the subsoil of the area differs from that known in literature, as it shows a single level of "Panchina" that rests directly above clay sediments of the Lower Pleistocene.

    The marine fossil malacofauna in a Plio-Pleistocenic section from Vallin Buio (Livorno, Tuscany, Italy)

    ABSTRACT
    In the present paper the occurrence of marine fossil malacofauna in a Plio-Pleistocenic section from Vallin Buio (surroundings of Livorno) is described. Three different mollusc associations are present. The oldest one is typical of the Italian Lower Pliocene, the other two, are characteristic of the Upper Pleistocene fauna. Specimens, sometime poorly preserved, are not numerous for each section, but all the identified species are compatible with the respective fossil associations. The fossil malacofauna in the calcarenitic level referred to the Upper Pleistocene shows a remarkable affinity with the biotic component of the posidonietum biocenosis.
