Abstract

Fieldwork around the lime-kilns at Zengővárkony (southern Hungary, eastern Mecsek Mts.) has led to the discovery of previously unknown beds of the Hidasivölgy Marl Formation. Based on bio- and lithostratigraphic considerations, here a Valanginian (Hauterivian?) age is assumed. This recently discovered section consists of thin-bedded, greybrownish turbiditic marls and limestones laid down in rhythmic alterations. Excavations of the marl beds have yielded a poorly-preserved, but rich cephalopod fauna. Furthermore, Eutrephoceras ex gr. boissieri has been identified here, and this is the first record of Cretaceous nautiloids from the Mecsek Mountains.
