Abstract
Two new brachiopod species of Jakutoproductus, J. lenensis sp. nov. and J. talchanensis sp. nov., are described. J. lenensis occurs in the upper part of the J. verkhoyanicus Zone of the Khorokytian Horizon (Asselian–Sakmarian deposits) of the lower reaches of the Lena River and in the Sobolokh-Mayan and Allara-Khadaryn’ya river basins. J. talchanensis is identified from the Khorokytian Horizon of the Talchan River (Baraiy River basin). A new subzone, the J. lenensis Subzone, is proposed for the upper part of the J. verkhoyanicus Zone of the Khorokytian Horizon of the Verkhoyansk Region.
