TAXONOMIC REVISION OF THE FAMILIES ARCIDAE AND NOETIIDAE (MOLLUSCA: BIVALVIA) OF THE MIOCENE OF THE SOUTH-WEST MARGIN OF THE EAST EUROPEAN PLATFORM

Abstract

Miocene sediments, which are widespread on the territory of Volyno-Podillia, are composed of multifacies marine, lagoonal, and partially continental sediments. Molluscs in the Neogene period on the territory of Volyno-Podillia were extremely developed and existed alongside such groups of fauna as brachiopods, foraminifera, serpulids, echinoderms, mollusks. Bivalves make up a significant share of them, which in some places are the only fossils suitable for determining age and biozonal division. In particular, the families Arcidae and Noetiidae are distinguished among bivalve molluscs, which are quite common in the Carpathian and Badenian stage of the southwestern edge of the East European platform. A taxonomic revision of the families Arcidae I Noetiidae (Mollusca: Bivalvia) from the Miocene sediments of the southwestern edge of the East European Platform was carried out on the basis of the stock collection stored in the State Natural History Museum of the National Academy of Sciences of Ukraine. A monographic description, detailed synonymy and images of four species are given: Barbatia barbata L., Anadara diluvii Lam., Anadara turonica Duj., Striarca lacteal L., and the geographical and stratigraphic distribution of these species in the Miocene time on the territory of the Volyno-Podillia plate is also clarified.
