Holotype.—Axial section (No. 23/1868, UTGU) from the Eife- lian of the northern Urals, Russia (Petrova, 1981, pl. 7, fig. 13).


Diagnosis.—Small species for the genus, characterized by a moderate number of necks, a relatively broad inner spherical chamber and a polygonal external chamber.


Occurrence.—Eifelian–Givetian of the western slope of the middle and northern Urals. Eifelian of the Tomsk area (SW Siberia). Givetian–Frasnian of the southeastern part of the western Siberian Plain. Discovered in the early Givetian of Mount Polinik (Carnic Alps, Austria).


Description.—Outer diameter=0.18–0.21mm; inner dia- meter=0.06–0.10mm; number of necks: (3)–6–8; test wall thickness(s)=0.02–0.05mm.


Remarks.—As for E. losvica, the taxon shares a wall of urali- nellid with a shape of parathuramminid; our material slightly differs from E. losvica by the less acute shape of protuberances. As indicated by our synonymy list, the genus assignment and the species spelling vary in the literature.


Materials.—20 specimens (samples POL11-8, POL11a-14a, POL11b-19c, POL11a-26a, and POL14-6a).

Holotype.—Fig. 8.20 (sample POL13a–4); Institute of Geology, University of Innsbruck, Cat. Nr. P 10141-POL 13a (thin sec- tion); early Givetian of Feldkogel Limestone (Polinik Forma- tion); Mount Polinik (Austria).


Diagnosis.—Elenella relatively large, spherical, but generally periphically poorly preserved. Central chamber subpolygonal with thick dark-microgranular wall. Necks more regular and thinner than the wall. Peripheral thin, dark-microgranular wall. Intermediary wall grayish recrystallized/filled by microsparite.


Occurrence.—Givetian of Mount Polinik (Carnic Alps, Austria).


Description.—Outer diameter=0.16–0.36mm; inner dia- meter=0.08–0.17mm; inner chamber wall thickness=0.01– 0.03mm; outer chamber wall thickness=0.06–0.08mm; num- ber of necks: 8–14 (their width is 0.01–0.02 mm).


Etymology.—After Mount Polinik (Carnic Alps, Austria).


Remarks.—Similar to the upper Emsian species E. monielli Vachard, 1991, the new species differs by a larger central chamber with a thicker wall, and fewer necks/trabecules within the wall.


Materials.—25 specimens (samples ?POL11b-14, POL13a-1a, POL13a-2, POL13a-3, POL13a-5, ?POL13a-5a, POL13b-4, POL13b-6, and POL13b-11).


Elenella sp. 3 Figure 8.23


Diagnosis.—The test is composed of two almost spherical, concentric chambers; the necks are long, thin and occasionally curved.


Occurrence.—Givetian of Mount Polinik (Carnic Alps, Austria).


Materials.—Only one specimen (sample POL14-9).


Family Uralinellidae Chuvashov, Yuferev and Zador- ozhnyi in Zadorozhnyi and Yuferev, 1984


Diagnosis.—Test bilocular, probably attached, at least tem- porarily. Inner chamber spherical, central or excentered. Outer chamber, larger, polygonal to ellipsoidal or subspherical. Radiate necks crossing through the space between the two chambers and often prominent at the periphery. Aperture inconspicuous or single at the extremity of each neck. Wall dark-microgranular, although this interpretation is often discussed.


Occurrence.—Late Silurian (Ludlovian)–latest Viséan of wes- tern and central Europe, former USSR (the Urals, Preural, eastern Russian Platform, western Siberia, Kyrgyzstan, and Tajikistan), up to early Tournaisian in South China, Vietnam, and Australia.


forms A and C sensu Veevers (1970, pl. 46, figs. 1–3, pl. 47, figs. 1–5); Sogdanina Saltovskaya, 1974; Arakavaella Pronina, 1963; Maclayina Saltovskaya, 1981; ?Ivdelina Malakhova, 1963 (= “well-preserved radiosphaerid calcispheres” sensu Berkyova and Munnecke, 2010, fig. 3A–D, 3F–I); ?Radiina Reitlinger, 1957; and ?Algaeformis Anfimov, 2012. Contrary to Vachard (1994), we consider that the latest Viséan genus Sog- danina is not synonymous with the Devonian genus Uralinella because its intermediary layer of the wall is entirely calcified (see for example Sogdanina sp. illustrated by Sanz-Lopez et al., 2005, pl. 6, fig. 9, under the name of Uralinella cf. U. augusta


Remarks.—The family Uralinellidae encompasses the follow- ing taxa: Uralinella Bykova, 1952; radiospherid calcispheres
