摘要

Six cyrtocrinid species, of which two are new, are described from the Lower Cretaceous calcareous and argillaceous marls of the Gerecse Mountains (northern Hungary): Phyllocrinus stellaris, Phyllocrinus sabaudianus, Phyllocrinus chalupai, Phyllocrinus bersekensis sp. nov., Apsidocrinus doreckae sp. nov., and Lonchocrinus dumortieri. For Lonchocrinus dumortieri, previously only recorded from the Bajocian to the Oxfordian, it is the youngest occurrence. Except for P. chalupai and the two new species, which seem to be endemic to this region, the other species are widespread in Jurassic and Cretaceous Tethyan deposits of Europe. The fauna to which these forms belonged most probably lived in water depths greater than 200 metres and in the presence of weak currents.
