Permian Nonmarine Bivalve Mollusks: Review of Geographical and Stratigraphic Distribution

详细

Data on global geographical and stratigraphic distribution of Permian nonmarine bivalves, which have not included in generalizing works are considered. The continental Permian beds of Euramerican, Angarian, Cathaysian, and Gondwanan paleozoogeographic realms are compared with reference to the nonmarine bivalve fauna from the Late Kungurian to Permian–Triassic boundary. It is concluded that the family Palaeomutelidae Lahusen, 1897 and also the genera Anadontella Betekhtina, 1987, Prilukiella Plotnikov, 1945, and Concinella Pogorevitsch in Betekhtina, 1966 are of the greatest significance for correlation of particular sections.
