Middle-Late Devonian Radiolarians
are recorded for the first time in the
southern Ural Mountains in Bashkortostan,
in a section of Kariukmas Mountain
(Upper Eifelian) and on the southern
slope of Argagan Mountain (Middle
Frasnian). The new Late Eifelian assemblage
is composed of 17 species of 11
genera, and Middle Frasnian radiolarians
comprise 13 species of 7 genera of
spherical, discoidal, pylomate, and spiny
radiolarians. A new species, Primaritripus
kariukmasensis, sp. nov., is described.
The prevalence of discoidal
forms in the oryctocenosis suggests shallow
marine conditions in the Late
Eifelian and Middle Frasnian basins.
Two new biostratons, the Upper Eifelian
beds with Primaritripus kariukmasensis
and Middle Frasnian beds with Primaritripus
chuvashovi, are established based
on radiolarians.

Late Emsian-Early Eifelian radiolarians
from the southern Ural Mountains
are recorded and described for the first
time. They come from the Kamennaya
Gora section on the Tanalyk River near
the town of Buribay, Bashkiria. The new
Late Emsian-Early Eifelian radiolarian
assemblage consists of 20 species of 11
genera of spherical, discoidal, spindleshaped,
pylomate, and spiny radiolarians.
Four new species, i.e., Entactinia rostriformis
sp. nov., Palaeodiscaleksus tumefactus
sp. nov., Primaritripus buribayensis
sp. nov., and P. chuvashovi sp.
nov., are described. The diagnosis of the
genus Primaritripus Afanasieva, 2000 is
amended. The fact that the oryctocenosis
is dominated by discoidal radiolarians
suggests that, in the Late Emsian-Early
Eifelian, the area under study was occupied
by a relatively shallow marine basin.
Based on radiolarians, a new Upper
Emsian-Lower Eifelian biostraton, beds
with Primaritripus buribayensis-
Entactinia rostriformis, is established.
The history of the study of Early Devonian
radiolarians is considered.

The genera Entactinia Foreman, 1963
and Stigmosphaerostylus Rüst, 1892 are
revised. The major differences between
the two genera are manifested in the
structure of the outer shell, internal spicule,
and the number of the main spines;
this suggests that they should be as-
