Various forms or species of Schwagerina ...Appearing commonly in the rocks of eastern Kansas are small wheat-grain-like fossils called foraminifers. These amoeba-like animals secrete a hard skeleton and grow to amazing size for one-celled organisms. The foraminifers in the upper left are termed fusulinids, derived from the Latin word for spindle (photo slightly enlarged). They were ...The developmental histories of fusulinid tests can be revealed in thin section. Axial thin sections (Fig. 1A,B), produced by grinding the test parallel to the coiling axis until the center of the initial chamber or proloculus is exposed, present the interior test morphology as well as the test's cross-sectional form of each whorl.They have yielded the famous Jambi flora, a typical Cathaysian plant assemblage. Recently Ueno et al. (2007) described Tethyan fusulinid faunas of Asselian age from these limestones. Early Permian ...Fusulinid foraminifera are commonly used for biostratigraphic correlations among Carboniferous to Permian strata in North America due to their high abundance in shallow-water carbonates and increasing diversity during the late Paleozoic (Koch and Frank, 2011; BouDagher-Fadel, 2018). Most fusulinids have a fusiform, or seed-like,Van Möller, 1878. The Fusulinidae is a family of fusulinacean foraminifera from the upper Carboniferous (Lower Pennsylvanian, Morrowan) to the Upper Permian ( Guadalupian ), tests of which are fusiform to subcylindrical with walls of two to four layers. Are planispirally coiled throughout or with early whorls at a distinct angle to the later ...Grains range in size from 0.5 to 6.0 μm, but grains larger than 4 μm are rare. Evidence that grains were secreted includes tight packing, uniform size and shape, and apparently homogeneous composition. Furthermore, scanning electron microscopy confirms the perforate nature of the antetheca and the nature of the keriothecal wall.The fusulinid faunas in both souther n and northern Afghani s-tan are closely related to those described from the type section of the Kube r-gandian Stage in the southeast Pamir [33] [34].Dictionary 0f Earth Science (Kamus Ilmu Kebumian) edisi kedua McGraw-Hill berisi cakupan disiplin ilmu kebumian (dalam bahasa Inggris)Fusulinid foraminifera are among the most common microfossils of the Late Palaeozoic and act as key fossils for stratigraphic correlation, paleogeographic and paleoenvironmental indication, and evolutionary studies of marine life.

The present study demonstrates comparable Late Carboniferous to Early Permian faunal successions between these two regions. Modified after Carpenter, 1850. Foraminifera are single-celled organisms (amoeboid protists) with calcareous shells that produce a network of reticulating strands of cytoplasm to catch food and live predominantly in seawaters.
