Olenekian brachiopods from the Kamenushka River basin, South Primorye: New data on the brachiopod recovery after the end-Permian mass extinction

Аннотация

The brachiopods (e.g., Heterelasma sp. nov., Uniplicatorhynchia sp. nov., Quadratirhynchia sp., and Sphriganaria sp.) discovered from the Olenekian deposits of the Kamenushka River basin and Russky Island, South Primorye, allow refining the information on the stratigraphic range of the relevant families and recovery of the biota after the Late Permian mass extinction. A new terebratulid genus, Bittnerithyris gen. nov., and a new rhynchonellid species, Piarorhynchella tazawai sp. nov., are established.
