The University of Kansas is a public institution governed by the Kansas Board of Regents. Fusulinids. Fusulinids were small marine organisms that were common inhabitants of the world's seas during the Pennsylvanian and Permian periods, from about 323 to 252 million years ago. The earliest fusulinids occur in rocks deposited during the late Mississippian Period, more than 323 million years ago. Fusulinids became extinct during the ...Late Moscovian-Early Sakmarian fusulinid faunas of the Anatolian Platform were exam-ined in three stratigraphic sections (Ozbek Tepe, Eskibey and Bademli) from the Eastern and Central Taurides.Fusulinid genera tend to be distributed patchy and within a broad facies range.

Here we present the results of 19 Pseudofusulina specimens, including high resolution images and rendered three-dimensional (3D) visuals of the important internal structures, to unwrap more details of fusulinid morphology. This is the first time the full 3D visuals of fusulinid interiors were constructed and exhibited.The fusulinid cyclic model developed for the Donets Basin represents a stratigraphic ‘symmetrical pattern’ in the terminology proposed by Brett (1998, p. 249). He noted that: “Within a single stratigraphic section, habitat tracking may produce a predictable vertical stacking pattern of biofacies that appear in a nearly symmetrical cycle.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 ...She discovered the Permian fusulinid assemblage described herein. This new microfauna is older than the first biozone of the Leonardian, but is different from all Latest Wolfcampian assemblages mentioned in the Americas, and contains several Tethyan taxa. This assemblage confirms that Guatemala received several migrations of Tethyan ...The Howe fusulinid assemblage is composed entirely of species of the genus Leptotriticites. The species L. hughesensis and L. glenensis were originally described from just beneath the new systemic boundary horizon in the Hughes Creek Shale Member and Glenrock Limestone Member, respectively.on fusulinid samples from the Kapitol Member of the Wordiekammen Formation. The Kolosseum section is located in the western part of the Nordfjorden High, central Spitsbergen (Figure 1).

This paper discusses the fusulinid biostratigraphy of the uppermost Pennsylvanian ("Bursumian") and Lower Permian (Wolfcampian) strati- gists in Japan. Ozawa's studies on fusulinid foraminifers of the Akiyoshi limestone were excellent at that time and have played a large part in biostratigraphic studies on the upper Paleozoic formations in Japan. It seems timely, however, that a restudy of the numerous fusulinid faunas of the Akiyo-shi limestone be made in the light of otherPaleozoic marine strata, and so the Howe fusulinid fauna is significant for the definition and correlation of the new systemic boundary throughout North America. Fusulinid assemblages from two Howe Limestone Member localities in northeastern Kansas (fig. 1) are discussed in this study. Carboniferous (Pennsylvanian)–Permian Boundarynorthern Urals and it includes the earliest fusiform fusulinid for-aminifers. Its widespread geographic distribution and short strati-graphic range led Thompson (1945, 1948) to erect the Zone of Profusulinella within his fusulinoidean subdivision of the North American Pennsylvanian System (now Subsystem).
