Fossils of Antiarcha (Vertebrata, Placodermi) in the Devonian of the Holy Cross Mountains (central Poland)

The paper indicates a similarity between remains of various Palaeozoic fishes thus hindering identification of fossil of Antiarcha—rare placoderms in the Holy Cross Mountains. A comparison of the vertebrate fossil assemblage from Lode Famennian delta deposits in Latvia with that from the Lower Devonian “Placoderm Sandstone” of the Podłazie hill in the Holy Cross Mountains (Poland) shows their similarity. It indicates a fluvial (?deltaic) origin of the “Placoderm Sandstone” from Podłazie. Additionally, fragmentary antiarch plates are revealed from the Frasnian of the Wietrznia Quarry in Kielce (Holy Cross Mountains)
