Sabirov). Ivdelina and “well-preserved radiosphaerid calci- spheres” (sensu Berkyova and Munnecke, 2010, p. 588) belong either to the Uralinellidae or to the Tuberitinidae. The genus Algaeformis, initially assigned to the Uralinellidae, more prob- ably belongs to the Auroriidae as redefined herein, as well as the genus Radiina.


Genus Uralinella Bykova, 1952 Type species.—Uralinella bicamerata Bykova, 1952.


Other species.—See Zadorozhnyi and Yuferev (1984) and Vachard (1994).


Diagnosis.—Uralinellidae with a well-developed, polygonal to subspherical outer chamber. Radiate necks crossing through the space between the two chambers, and markedly prominent at the periphery. Aperture single at the extremity of each neck. Wall dark-microgranular, apparently formed by an inner layer around the inner chamber, and an outer layer at the periphery. Calcified


wall of the necks and hollow intermediary spaces secondarily filled by neosparite.


Occurrence.—Early Devonian of Tajikistan. Late Devonian of northern Spain. Middle Devonian of the northern and central Urals, western Siberia, Zeravchan Gissar and Turkestan ranges (Kyrgyzstan, Tajikistan). Givetian of western France and Morocco. Late Devonian of Molotov area, Bashkorotostan, Tatarstan, Urals, and SW Siberia (Russia), Moravia (Czech Republic), and Belgium. Latest Famennian–early Tournaisian of Greece (Vachard and Clément, 1994), central Urals (Chuvashov, 1965), Tian Shan (Poyarkov, 1969), South China (Wang, 1987), Vietnam (Doan in Tong et al., 1988) and Australia (Veevers, 1970; Stephens and Sumner, 2003).

Holotype.—Axial section (No. 92/1868, UTGU) from the Middle Devonian of the northern Urals, Russia (Petrova, 1981, pl. 11, fig. 17).


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


347


Occurrence.—Early Devonian of Tajikistan and western Siberia. Eifelian of Tomsk area (SW Siberia). Middle Devonian of the northern and central Urals. Frasnian of SW Siberia. Discovered in the Givetian of Mount Polinik (Carnic Alps, Austria).


Description.—Test outer diameter=0.09–0.18mm (0.09– 0.12mm; rarely 0.18–0.20mm for the type material); test inner diameter=0.05–0.12mm(0.05–0.09mmfor the type material); number of necks: 3–6(4–5 for the type material); inner diameter of necks=0.005–0.008mm; test wall thickness=0.005– 0.001mm (0.008–0.013mm for the type material).


Materials.—24 specimens (samples POL11-11, POL11-13, POL11a-1, POL11a-27, POL11a-27a, POL11a-28, POL11b- 16. 25, and POL13b-3).

2016a Uralinella spp.; Vachard, fig. 3.4?, 3.7, 3.8, 3.13, 3.16, 3.18?, 3.24?.


Holotype.—Fig. 10.8 (sample POL11a–3); Institute of Geology, University of Innsbruck, Cat. Nr. P 10139-POL 11a (thin sec- tion); Givetian of the Feldkogel Limestone (Polinik Formation); Mount Polinik (Austria).


Diagnosis.—This species of Uralinella is characterized by the greater number of canals; small size; thin wall, and a festooned profile of the second chamber.


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


Description.—Outer chamber=0.12–0.23mm; inner cham- ber=0.06–0.10mm; number of canals: 9–12, mainly 10; test wall thickness=0.005–0.006mm, rarely 0.01mm.


Etymology.—Named in honor of A.A. Sabirov, for his con- tributions to parathuramminid micropaleontology.


Materials.—10 specimens (samples POL11a-3, POL11a-5, ? POL11a-26, POL11b-19c, POL11b-23, ?POL13a-2, and ? POL13b-8).


Remarks.—Differs from U. antiqua by the greater number of canals, and fromU. bicamerata andU. parva Sabirov, 1974 by a smaller size, more canals, and a festooned profile of the second chamber.


Family Parathuramminidae Bykova in Bykova and Pole- nova, 1955 emend. Vachard, 1994


Diagnosis.—Test free or rarely atttached, unilocular with a globular to polygonal chamber with rare to abundant tubular, mamillate, or subconical projections variously arranged and developed; wall dark-microgranular, occasionally with an inner
