Abstract
A new poteriocrinid genus, Magnofossacrinus, represented by the type species M. domodedovoensis sp. nov. from the Upper Carboniferous deposits of the Moscow Synecline, is described. The new genus is the youngest (Moscovian stage) reliable representative of the family Poteriocrinidae. Magnofossacrinus is characterized by unusually large cirrus with polynodal articular facets. The morphology of Magnofossacrinus stems is discussed and compared with the stems of other closely related crinoids.
