Summary: | 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. |
