FŰKÖH, L.: Main features of the development of the Hungarian Holocene Mollusc fauna

Bulgarica vetusta Laciniaria turgida Zonitoides nitidus Vitrea subrimata Oxychilus inopinatus Oxychilus draparnaudi Daudebardia brevipes Daudebardia helenae Trichia hispida Semilimax kotulai Perforatella vicina Monacha cartusiana known only from atlantic sediments its first appeareance is known in the subatlantic phase known only from the latest subatlantic fauna known only from the latest subatlantic fauna known only from the latest Holocene deposits (subboreal, subatlantic phases) known only from the sediments of the subatlantic phase it isn't found in boreal sediments known only from the sediments of the subatlantic phase known only from the sediments of the latest Holocene fauna (subboreal and subatlantic phases) known only from the Early-Holocene deposits (boreal and atlantic) known only from the subatlantic phase it appears during the subatlantic phase In the present period of the investigations we can state that the appeareance of the following mollusc species can be traced only from the Late-Holocene at the Hungarian Mountain-ranges of medium height: Vertigo antivertigo, Laciniaria turgida, Zonitoides nitidus, Oxychilus draparnaudi, Daudebardia helenae Perforatella vicina, Monacha cartusiana. Among the recent mollusc species the only one wich is not known from Holocene sediments of the mountain ranges of medium height is the Helicella obvia up to now. Development of the Holocene Mollusc fauna of the Hungarian subsided zones During the author's examinations there have been 33 species found. Species which occur only in a certain period of the Holocene from significant proportion of the fauna (21 species). It is caused by the insufficient examinations of the outcrops. But there are species which lack or presence is significant feature of the sediments.
