The perforation of the dorsal valve continues in a long tube which joins a short collar of the ventral valve. In slightly opened shells a narrow gap appears between the collar and the tube. The posterior part of the gap is near the rim of the ventral collar. In the new model of the feeding mechanism of pygopides this feature involves that the exhalant jet passed directly over the ventral entrance of the tube. The propulsion of the exhalant jet might generate a low-pressure regime in the tube. An advantage of this process is increasing circulation through the mantle cavities of the lateral lobes, by the sucking effect of the low-pressure regime. The pygopide might lift itself from the mud by contracting the adjustor muscles of its pedicle. The underlying unconsolidated mud is stirred up and the fine grained organic-rich material may be sucked into the low-pressure area of the tube. Then this suspended matter might be ejected off the tube and the food might be recycled by the inhalant currents. With 14 figures and one table.

On the basis of 11 identified ammonoid species, the Balatonicus and Trinodosus zones have a complete record. The stratigraphical position of the Zuhánya Limestone on the whole corresponds to the Felsőörs Limestone in the Balaton Highland. The palaeobiogeographical evaluation of the cephalopod fauna showed that the elements of the nautilid fauna point mostly to Germanic and partly to Sephardic affinity. On the other hand, the ammonoid fauna has no Germanic elements; most of the species are Alpine in character, while the species Procladiscites brancoi indicates Dinaridic connection, or at least an occasional appearance of pelagic organisms. These results endorse the previous palaeogeographical assumption and suggest that during the Middle Triassic the Mecsek succession was situated along the European shelf, between the Vindelician-Bohemian Land and the open Tethyan Ocean.

AB - The stratigraphic and paleoecologic investigations of the Middle Triassic Kádárta section of the western part of the Transdanubian Range (Hungary) let an insight to the drowning of an isolated carbonate platform and the deposition of the following pelagic successions in deep neritic and bathyal environment. The biostratigraphic and radiometric ages revealed the presence of a gap between the Pelsonian (Middle Anisian) shallow-marine carbonates and the overlying deep-water succession, since the onset of pelagic sedimentation was dated as late Illyrian (latest Anisian). This suggests that the study area was located on a relatively high paleotopographic position after the break-up of the Neotethys in the late Pelsonian. Correlation with other localities of the western Neotethys indicates that some sections were located either on rapidly subsiding blocks (e.g., Klisura – Dinarides, Schreierkogel – Northern Calcareous Alps, Baradla Cave – Aggtelek-Rudabánya Unit) or on more emerged highs (Rid – Dinarides). The integrated ammonoid and conodont biostratigraphy accompanied by Usingle bondPb ages provided a good opportunity for correlations with Ladinian key sections (Bagolino, Monte San Giorgio, Rio Nigra) from the Southern Alps.

AB - New material and the investigation of old collections provided some 150 specimens of Early Cretaceous brachiopods from the Mecsek Mountains, Hungary. Taxonomic evaluation resulted in the identification of some species previously unknown from Hungary and confirmed the presence of some previously described species, too. In this paper Fortunella cf. fortunae Calzada, 1985, Lacunosella hoheneggeri (Suess, 1858), Monticlarella remesi Nekvasilova, 1977, Moutonithyris moutoniana (d’Orbigny, 1847), Karadagella ? aff. bilimeki (Suess, 1858), Nucleata veronica Nekvasilova, 1980 are described. This fauna is rather endemic. All the specimens reveal a unique phenomenon: they exhibit 25‒70% larger average dimensions compared to populations of their closest relatives or type localities. The uniform size increase of these brachiopods may be linked to hydrothermal processes of the sea-floor. Lately, a discovery from the Tyrrhenian Sea offers a Recent, present day analogue to this enigmatic palaeoenvironment. Palaeobiogeographic comparison of this small endemic fauna with eight others, mainly Hauterivian and Tethyan brachiopod assemblages reveals the distinct Sub-Tethyan domain consisting of the faunas from Zengővárkony, Codlea (Eastern Carpathians) and Štramberk (Czechia). This strengthens previously described affinities and relationships of these faunas and helps to clarify the Cretaceous palaeogeographic position of the Mecsek Mountains. LA - English DB - MTMT ER -
