Lower and Middle Jurassic Gastropods from the Bakony Mts. (Hungary) Part I. Euomphalidae (Archaeogastropoda) by J. SZABÓ, Budapest Abstract — Three Liassic of the here described seven Discohelix species are new : D. inornala sp. n., D. miocarinata sp. n., D. acarinata sp. n. Three Pentagonodiscus species are described, of which one Liassic is new: P. initiopentagonatus sp. n. An exceptional Pentagonodiscus angustus WENDT, 1968, specimen proved that in the formation of the parabolic sculptural elements no resorbtion had role. With 5 figures and 2 plates. Introduction — In the last decade the Hungarian Geological Survey excavated several artificial exposures in the Jurassic of the Bakony Mts. (Transdanubian Central Mountains), and these exposures yielded a rich (approximately 800 specimen) gastropod fauna. The gastropod finds were associated with ammonites in all cases that made a precise Fig. 1.
