Abstract

There are important morphological differences between the dominant higher taxa (classes) in associations of radiolarians that inhabited different depths of paleobasins. A similar inversion of dominant radiolarian taxa can be seen in the Early Tournaisian (Mississippian) and the Kungurian (Cisuralian) and may indicate a change in their habitat from deeper conditions dominated by porous Sphaerellaria, to shallower shelf environments, in which spongy-lattice Spumellaria prevailed.

俄罗斯东欧早图尔奈斯期（密西西比期）和昆古里亚期（西苏拉期）放射虫组合的变化模式

摘要在古盆地不同深度栖息的放射虫类群中，主要的高等类群（类）之间存在着重要的形态差异。在早图尔奈斯期（密西西比期）和昆古里亚期（西苏拉利亚期）也可以看到类似的主要放射虫类群的反转，这可能表明它们的栖息地发生了变化，从以多孔藻类为主的深海环境转变为以海绵状格子藻类为主的浅海陆架环境。

期刊介绍： Paleontological Journal (Paleontologicheskii zhurnal) is the principal Russian periodical in paleontology. The journal publishes original work on the anatomy, morphology, and taxonomy of fossil organisms, as well as their distribution, ecology, and origin. It also publishes studies on the evolution of organisms, ecosystems, and the biosphere and provides invaluable information on global biostratigraphy with an emphasis on Eastern Europe and Asia.
