Palaeobiogeographic analysis of Moscovian (Pennsylvanian) brachiopods Productida, Orthotetida, Orthida, Rhynchonellida from Bükk Mts, Hungary

Two brachiopod faunas from the Moscovian of the Bükk Mts are discussed in the present paper. This paper deals with the Productida, Orthotetida, Orthida, and Rhynchonellida. The outcrops are along the railwaycuts near Nagyvisnyó (Bükk Mts Hungary), at hectometer 416 and 422. The two outcrops contain different faunas in the shales. Eleven families, 25 genera and 33 species. The most abundant elements are Linoproductus cora (D’ORBIGNY) and Chaoiella gruenewaldti (KROTOW). The fauna of Nagyvisnyó railway cut 422 is closely related to Early Moscovian faunas of Cantabrian Mts, Carnic Alps, Karavanke Mountains, and Western Serbia because of the occurence of Rugosochonetes acutus (DEMANET) Avonia cf. echidniformis (CHAO), Kozlowskia pusilla (SCHELLWIEN), Karavankina rakuszi WINKLER PRINS and Echinoconchus species. The age of the fauna of railwaycut 416 is hard to determine because it contains no stratigraphicaly important species. Possibly, it is younger Moscovian. Both faunas were transported but the fauna of 422 possibly over longer distance
