These communities, all of late Arenig age (Klabava Formation), are known from the western part of the Prague Basin, Bohemia. They are characterized by a prevalence on orthid brachiopods in their taxonomic composition, with less abundant inarticulate brachiopods, trepostomate bryozoans, hexactinellid sponges, gastropods, ostracods and trilobites. The taphonomy of their occurrences indicate transportation, disarticulation, fragmentation, and size-sorting of skeletons, with no allochthonnous fossil assemblages, and the dominance of adult valves in size frequency distributions of the commonest species. All benthic communities occuppied shallow subtidal up to intertidal, purely marine environment.
