O Goulandris Natural History Museum, 14562, Ki¢ssia, Athens, Greece. P 28 Jacob Drive, Whitby ON, Canada L1P 1B1. $Corresponding author, e-mail: [email protected] Species of marine bivalve molluscs identi¢ed in the last nine years in the Greek waters have been used to update the checklist published in 1996 (Fauna Graeciae VII ) by inserting necessary changes and adding new records. The updated version includes 13 new species among which 3 are exotics (non-Mediterranean species), 5 rare, 2 new deep sea and 1 previously considered a fossil species. Also, as a result of new resources, the distributions of preexisting native molluscs have been updated to include new habitat areas. The nomenclature is also up to date based on the CLEMAM Database. Thus 5 species are now excluded either because they are junior synonyms of pre-existing valid species (2) or because of old spurious records (3 species). Additions and corrections of the 1996 checklist have resulted in a total of 308 bivalves in Greek waters. INTRODUCTION areas where more detailed studies have been completed (e.g. Evvoikos Gulf and Saronikos Gulf ). Research over the last two decades in the Eastern The nomenclature followed in this study is that of Mediterranean has revealed new geographic areas, new Sabelli et al.

Two main marine units are recognised, labelled CNM and ALT, separated by an angular unconformity and formed by elementary depositional sequences (CNM1-4, ALT1-5).

Of these, 10 are dubious records (7 Gastropoda and 3 Bivalvia), there remaining 225 confirmed taxa in this island.

Radial ribs can be defined as ribs of Ostreoidea and Plicatuloidea are formed by a helicospirals that diverge from the umbo and represent the mantle margin which, upon extension from the shell growth trajectories of particular portions of the mantle margin, stretches and folds by taking the preformed ribs specialized for rib secretion, which were identified and as templates.

Keywords: Museum dark data; museology; paleoecology; Neogene Mediterranean molluscs; biodiversity. Abstract. The upper Miocene mollusc collection from Monti Livornesi, Italy, collected more than a century ago, is confronted with new collections coming from the same localities of Popogna and Quarata. The study concerns the comparison of abundance data of three distinct fossil assemblages from the three vertically-stacked stratigraphic units called Luppiano, Rosignano and Raquese, of upper Tortonian-early Messinian age. Literature and museologi- cal data allowed to attribute most museum specimens to one and only one fossil assemblage. Museum collections preserve roughly the same dominant species, with similar ranks as the new quantitative field collections.

ABSTRACT - The integration of sedimentary facies analysis, ichnology and benthic mollusc quantitative paleoecology allowed interpretation of factors that have controlled the deposition of the alluvial to marine succession outcropping in Northwestern Sicily (Southern Italy) at Altavilla Milicia, near Palermo (Imerese Basin). Two main marine units are recognised, labelled CNM and ALT, separated by an angular unconformity and formed by elementary depositional sequences (CNM1-4, ALT1-5).
