Abstract

The present paper deals with a brachiopod fauna collected from four localities of the Balaton Highland. The systematic studies showed the presence of 35 taxa, of which two species have first record in Hungary, and three other seem to be new. The abundant material has been examined from the point of view of paleoecology, paleobiogeography, stratigraphy, evolution, and statistical methods. The paleoecological study allowed to interpret the differences in faunal distribution of the four localities as the consequence of different habitats and conditions of fossilization due to the varied bottom relief of a shallow-water shelf environment. The comparison with a number of other Anisian brachiopod faunas shows strong affinity to those in the Southern Alps and in the Western Carpathians. The relative stratigraphic position of the three main sections was clarified by using other authors' data based on ammonoids. The stratigraphic differences of the fossiliferous Recoaro Limestone remain within the boundaries of the Pelsonian Substage. It was possible to determine the stratigraphic range of some traditional index species (Decurtella decurtata, Piarorhynchella trinodosi) more precisely. New data concerning the evolutionary links of rhynchonellids made possible to trace back two important lineages of this group. - from English summary
