Abstract
New radiolarian taxa are described from the Lower and Middle Famennian of the Polar Urals and Volga–Urals Basin: three new genera Natgorella gen. nov., Spinoalius gen. nov., Diversiacus gen. nov., and three new species N. elegans sp. nov., N. hirsuta sp. nov., and S. melekessensis sp. nov. New taxa belong to two orders, Entactiniata and Cancelliata, of two classes of spherical radiolarians: Sphaerellaria and Spumellaria. Morphotypes of the outer skeletons of Spinoalius gen. nov. and Diversiacus gen. nov are shown to be convergently similar. A new Middle Famennian Natgorella hirsuta–Spinoalius melekessensis radiolarian ecozone is established.
