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.

The lithological and geochemical composition and conditions of formation of the coal-bearing deposits of the Kizel Coal Basin in the Perm region of the Urals(central Russia)are described using the two most representative sections,Gubakha-Stary Most and Krestovaya Mountain,based on a detailed“layer-by-layer”*** characteristics of the Lower Carboniferous paleosols from fossil paleosol(FPS-)profiles of the studied region are *** attention is paid to the parent vegetation of the coal-forming processes,based on an analysis of both plant macrofossils and *** peat accumulation in conditions of permanent incoming of clastic material from the Paleo-Urals to the Kizel Basin was probably effective only in more or less stable environments,when the accumulated organic matter produced by plant mortmass was not dissolved by clastic ***,the conditions of coal-forming are reconstructed as a forest swamp,where the main dominants are represented by lycopodiopsids of the order Lepidodendrales,predominantly Lepidodendron *** plants in particular were the source of the initial organic matter for the peat(and later coal)of the Kizel Coal Basin.

The paper deals with the Lower Kungurian （Philippovian Horizon; Lower Permian） biota of the Mid-dle Cis-Urals, Russia. The biota is characterized on the basis of four representative localities （ Philippovskoe Bus-stop, Philippovskian Quarry, Kamai and Kiselevo-Suksun Highway） , which are situated in the stratotype area of the Kungurian stage. All the localities can be regarded as Lagerstatten, but of authentically low biodi-versity ,since they represent oligotrophic lagoons of abnormal fluctuating salinity. General reconstruction of the Philippovian near-shore shallow-water ecosystem is given. Two new species of algae Algites philippoviensis sp. nov., A. shurtanensis sp. nov., and a new species of the limulids Paleolimulus kunguricus sp. nov. are de-scribed for the first time.

The Huadu flora of Guangdong Province, South China contains the lepidodendrid Lepidodendron shanyangense Wu et He, its putative rhizophore Stigmaria cf. ficoides （Brongniart） Sternberg; sphenophyte s.l. Archaeocalamites scrobiculatus （Brongniart） Stur; bowmanitid Sphenophyllum tenerrimum （Ettingshausen） Stur; pteridophyll Sphenopteris sp. of uncertain taxonomic position; undetermined ferns gen. et sp. nov.; lyginopterid pteridosperm Rhodeopteridium hsianghsiangense （Sze） Zhang, Zhao et Wu, a trigonocarpoid pteridosperm represented by fronds and isolated pinnules of Paripteris gigantea （Sternberg） Gothan, male fructifications of Potoniea sp., and seeds of Trigonocarpus sp. Ecologically, the Early Carboniferous （visean） Huadu vegetation was divided into two neighboring communities：（1） a near-shore hydrophilous ＂community A＂ with predominating Archaeocalamites and Rhodeopteridium; and （2） a wet forest ＂community B＂ with predominating shrubby trigonocarpalean pteridosperm Paripteris gigantea （Sternberg） Gothan and tall tree-like lepidodendrid Lepidodendron shanyangense Wu et He. The Huadu vegetation was physiognomically similar to present-day low-latitude mangrove forest.
