Skamieniałości Antiarcha (Vertebrata, Placodermi) w dewonie Gór Świętokrzyskich
Abstract
Fossils of Antiarcha (Vertebrata, Placodermi) in the Devonian of the Holy Cross Mountains (central Poland).
Summary. 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 Pod³azie 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).
