Abstract
Field work focused on the Kuedinskie Kluchiki locality,Perm region,Urals,Russia,which contains a rich assemblage of diverse fossil organisms including higher plants(equisetophytes,pteridosperms,ginkgophytes,conifers,vojnovskyans)represented by stems,leaves and reproductive organs;invertebrates(mollusks,arthropods),and tetrapods(temnospondyl amphibians,seymouriamorphs,cotylosaurs,synapsids,diapsids),as well as bony fishes.General characteristics of the taxonomical composition of the Kuedinskie Kluchiki locality are given.A new peltaspermalean pteridosperm taxon,Compsopteris longipinnata sp.nov.,and a voltzialean conifer Archaeovoltzia kuedensis sp.nov.are described.General considerations on the paleoecologic and paleogeographic conditions of the Kuedinskie Kluchiki locality origin are given.
