Resumo

On the base revision of core samples from the Research Institute of Geology Oles Honchar Dnipropetrovsk National University the micropaleontological characteristic of Dobrudja Foredeep Miocene (Odessa region) and the first monographic describes of foraminifera and ostracods of these deposits are given: Discorbis figuratus Konenkova, Discorbis ukrainicus Satanovskaja, Ammonia maschanliensis (Pronina), Ammonia subbeccarii (Pronina), Ammonia simplex (d’Orbigny), Ammonia nativa Konenkova, Cytherois aff. gracilis Schneider, Pseudobythocythere dromas (Schneider), Falunia ex gr. plicatulla (Reuss). Deposits of the Konkian and Chokrakian Regiostages are set. The Majachkian Suite is characteristic. For the first time an endemic foraminifera Ammonia subbeccarii (Pronina), Ammonia nativa Konenkova are found in this suite. It is helped to define Tarkchanian age of the Majachkian Suite. It sets a different age the "Comrat layers" in the sections of two wells in which this straton was established. This was the basis for the recognition of invalidity the "Comrat layers" and the inability to synchronize them with the Chornobaivka Suite of the Northern Black Sea region. Key words: Miocene, Komrats Layers, Majachkian Suite, Tarkchanian, Chokrakian, Konkian, Sarmatian, foraminifera, ostracods, Dobrudja Foredeep, Western Blasck Sea region, Southern Ukraine, Eastern Paratethys.
