Abstract (in english)
   The occurrences of Silurian and Devonian phyllocarids of Bohemia demonstrate the environmental dependence and changes in assemblages with clear analogies in other regions. Low energy, commonly offshore (shale, platy limestones) facies yield frequent, widely distributed and persistent, presumed nektonic forms (e.g. Ceratiocarididae). Reef facies are typified by locally rich assemblages of benthic or nektobenthic phyllocarids (especially aristozoids and some echinocarirdids), which only occasionally occupied the former biotopes. The most important evolutionary and event-influenced changes in assemblages are shown by the replacement of ordovician Caryocaris Assemblages by Silurian Ceratiocaris - dominated ones; by the rich development of aristozoids within the Lower Devonian, and ba a late Middle devonian innovation: the wide expansion of echinocaridids and rhinocaridids, which continue up to the Lower Carboniferous. The subgenus Ceratiocaris (Bohemicaris) n.subgen. is established
