The paper deals with the Lower Kungurian( Philippovian Horizon; Lower Permian) biota of the Middle 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 Lagersttten,but of authentically low biodiversity,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 described for the first time. 相似文献
