- Abstract
A new collection of brachiopods made in 2003 from lower Pragian beds of the northeastern part of Heceta Island of Southeast Alaska allows us the opportunity to reevaluate some of the rhynchonellid and atrypid brachiopods that were previously described by Kirk & Amsden (1952) and Savage (1981) from the same locality. We here describe the following taxa: Kirkirhynchus gen. nov. with Ancillotoechia reesidei Kirk & Amsden, 1952 designated type species, Savagerhynchus hecetaensis gen. et sp. nov., Dubovikovia cf. kuzmini (Cherkesova, 1968) and Rugosatrypaflexibilis (Cherkesova in T. Modzalevskaya & Cherkesova, 1994). The occurrence of the two last species allows correlation of the lower Pragian beds of Heceta Island with Uryumskay, Tolbatskay and basal part of Daksanskay layers of Taimyr, Russia and the Soda Creek Limestone of west-central Alaska. Close faunal ties are clearly evidenced by Pragian brachiopod faunas of Southeast Alaska, southwest Alaska, Northeast Asia, and Taimyr.
