New Rhynchonellids and Atrypids (Brachiopoda) from the Lower Devonian Deposits of Northeast Eurasia

Abstract—

The rhynchonellid Dogdoa talyndzhensis Baranov, sp. nov. (subfamily Dogdoinae) and the atrypid Vagrania naanchanensis Baranov, sp. nov. (subfamily Vagraninae) are described from the Lower Devonian deposits of Northeast Eurasia. Trails with preserved thin striae and concentric growth lines were found for the first time in the species Vagrania kolymensis (Nalivkin, 1936). The subfamily Punctspinatrypinae Baranov, subfam. nov. includes two genera: Punctspinatrypa Rzhonsnitskaya, and Mishninia Baranov, gen. nov with the reference species М. nodosa Baranov, sp. nov.
