Abstract

For the first time, the rhynchonellids Dubovikovia kuzmini (Tcherkesova, 1969), D. tarejaensis (Tcherkesova, 1969), and Tamarirhynchia varia (Tcherkesova, 1969) earlier known only in the Central Taimyr region, are described from Pragian basal beds in West-Central Alaska and Northeastern Eurasia. A new Alaska biogeographic province is recognized in the Arctic paleobiogeographic realm.
