Skamieniałości Antiarcha (Vertebrata, Placodermi) w dewonie Gór Świętokrzyskich

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).

The first articualted antiarch, Bothriolepis jazwicensis sp. nov., from the lowermost Fammenian (Upper Devonian) of the Jaźwica Quarry (Łgawa Hill) near Kielce, in the Holy Cross Mountains (central Poland), is described. B. jazwicensis sp. nov. Is distinguished from all other species of Bothriolepis especially by possessing long and narrow armour and many unusual proportions of the head-shield and trunk-shield plates. This is the most complete specimen of a placoderm ever found in the Holy Cross Mountains and its state of preservation precludes its longer post mortem transport.
