摘要
The rhynchonellidDogdoa talyndzhensisBaranov, sp. nov. (subfamily Dogdoinae) and the atrypidVagrania naanchanensisBaranov, 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 speciesVagrania kolymensis(Nalivkin, 1936). The subfamily Punctspinatrypinae Baranov, subfam. nov. includes two genera:PunctspinatrypaRzhonsnitskaya, andMishniniaBaranov, gen. nov with the reference species\M. nodosaBaranov, sp. nov.
