Fish remains from the Lower Cretaceous (Valanginian-Hauterivian) of Hárskút (Hungary, Bakony Mts)

Lower Cretaceous (Valanginian-Hauterivian) fish remains, collected in the Közöskút Ravine (nearby Hárskút, Hungary) in the 1960s are detailed here. Although the material is poorly preserved, it is of great importance, because this geographical region and stratigraphical provenance are relatively undersampled for marine vertebrates. The collected material includes four orders of fish: Hexanchiformes, Synechodontiformes, Semionotiformes and Pycnodontiformes. This is the first, actualized report of some of the Hárskút fish taxa from the Mesozoic of Hungary. The results add important data to the distribution of the identified taxa, especially to that of Gyrodus. With 20 figures and 1 table.
