Abstract

An analysis of the morphological features of the radiolarian skeletons of the class Stauraxonaria from the Late Carboniferous and Early Permian of the South Urals of Russia and the Western Mugodzhary of Kazakhstan, as well as the Middle Permian of Western Texas in the United States made it possible to reinstate the genus Nazarovispongus Kozur, 1980 and revise the systematic position of the species N. pavlovi and N. permicus established by Kozur (1980). The diagnosis of the reinstated genus Nazarovispongus Kozur, 1980 sensu Kozur et Mostler, 1989, restituo et emend nov. is emended, and the species composition is expanded to include six species: N. pavlovi Kozur, 1980 (type species), N. aequilateralis (Nazarov in Isakova and Nazarov, 1986, comb. nov.), N. delicatus (Nazarov et Ormiston, 1985, part., comb. nov.), N. globosus Nestell et Nestell, 2010, N. inflatus (Nazarov et Ormiston, 1985, comb. nov.), and N. subrotundus (Nazarov in Isakova and Nazarov, 1986, comb. nov.). A new genus Kozurispongus gen. nov. is described, to accommodate six species: K. aktastiensis (Nazarov et Ormiston, 1993, comb. nov.), K. circumfusus (Nazarov et Ormiston, 1985, comb. nov.), K. permicus (Kozur, 1980, comb. nov.), K. semilaminus (Nazarov in Isakova and Nazarov, 1986, part., comb. nov.), and two new species K. concavilatus sp. nov. and K. rotundatus sp. nov. A new scheme of sequential stages of the formation of skeletal spines is proposed.

来自晚石炭世 - 中二叠世的 Stauraxonaria 类放射虫：Nazarovispongus Kozur sensu Kozur et Mostler，restituo et emend。十一月 和新属 Kozurispongus gen。十一月

摘要

对俄罗斯南乌拉尔晚石炭世和早二叠世和哈萨克斯坦西穆戈贾里以及美国德克萨斯州西部中二叠世的 Stauraxonaria 类放射虫骨骼的形态特征进行了分析恢复Nazarovispongus Kozur属，1980 年，并修改Kozur (1980) 建立的N. pavlovi和N. permicus物种的系统位置。恢复的Nazarovispongus Kozur属的诊断，1980 sensu Kozur et Mostler，1989，restituo et emend nov。修订，物种组成扩大到包括六个物种：N. pavlovi Kozur，1980（模式物种），等边猪笼草（Nazarov in Isakova and Nazarov，1986，comb. nov.），熟猪笼草（Nazarov et Ormiston，1985，part.，comb. nov.），N. globosus Nestell et Nestell，2010，N. inflatus（ Nazarov et Ormiston，1985，comb. nov.）和N. subrotundus（Nazarov in Isakova and Nazarov，1986，comb. nov.）。一个新属Kozurispongus gen。十一月 被描述为容纳六个物种：K. aktastiensis (Nazarov et Ormiston, 1993, comb. nov.), K.circumfusus (Nazarov et Ormiston, 1985, comb. nov.), K. permicus (Kozur, 1980, comb. nov.), K. semilaminus(Nazarov in Isakova and Nazarov, 1986, part., comb. nov.)，以及两个新物种K. concavilatus sp.。十一月 和K. rotundatus sp。十一月 提出了一种新的骨刺形成顺序阶段方案。
