Abstract
This study is based on specimens of the family Marginellidae Fleming 1828 from the Miocene (Tortonian) of South Piedmont sites in the surroundings of Stazzano (Alessandria): Rio di Bocca d’Asino, S. Agata Fossili and Castellania. Seven species are here reported, three of which described as new (Dentimargo elusiva, Eratoidea antoniae, and "Marginella” giuntellii), three already known [Stazzania marginata (Michelotti 1847), Volvarina oblongata (Sacco 1890), and Marginella deshayesi Michelotti 1847] and one identified only at generic level (Volvarina sp.). The distribution of the genus Dentimargo is extended to the Miocene (Tortonian) of Italy. Dentimargo has a wider distribution, and was already known from the Eocene of France and the Pliocene of Spain. Eratoidea antoniae is compared with the syntype of E. eratoformis (Hoernes & Auinger 1880) and with specimens of E. cf. eratoformis from the Pliocene of Estepona (Spain), here figured.
