- Abstract
Taphonomy, stratigraphical occurrences and geographical distribution of Devonian placoderms in the Holy Cross Mountains described by former researchers is revised. Four main types of preservation states occur in the placoderm fossils of that region. Fossil preservation depends on geodynamic processes. Mechanical damage appears to be the main factor explaining the final state of preservation. For most of the previously described as well as the new specimens, the occurrences were dated biostratigraphically by palynomorphs and conodonts. The taxonomic distribution of placoderms in space and time within the Devonian strata in the Holy Cross Mountains correlates well with the Devonian nekton revolution, but it is also controlled by the regional palaeoecology and local synsedimentary tectonics of the carbonate platform.
