The continental fish fauna of the Late Cretaceous (Santonian) Iharkút locality (Bakony Mountains, Hungary)

The Late Cretaceous (Santonian) fish fauna of the Iharkut vertebrate site (Bakony Mountains, Hungary) is described here. The ichthyofauna includes the lepisosteid Atractosteus sp., the pycnodontid cf. Coelodus sp., Vidalamiinae indet., a non-vidalamiin Amiidae indet., Elopiformes indet., two indeterminate ellimmichthyiforms, cf. Salmoniformes indet., Acanthomorpha indet., at least one indeterminate teleostean, and numerous indeterminate actinopterygians (represented by teeth). Among these taxa, the Iharkut remains of Vidalamiinae and the suggested indeterminate Salmoniformes represent their first occurrence in the Late Cretaceous of Europe. The unidentifiable specimens may suggest the presence of further fish taxa. The gar remains described here further support the Atractosteus sp. affinity of the Iharkut form. Most of the Iharkut fishes are carnivorous, but durophagous taxa are also represented. Although chondrichthyan remains have not been identified in the Iharkut vertebrate material up to now, the eco...
