Journal of Paleontology 5, 253 –9.The fusulinids represented in these sa1nples include several genera characteristic of rocks of Middle Penn­ sylvanian age and include N ankinella, Staff ella, Pseudo-8t(tffella, F1.ls1.tlinella,, and F1.~J8uUna. The species are relatively primitive forms and as such do not suggest latest Middle Pennsylvanian age. As no fusulinids haveThe fusulinids are among the earliest calcareous-walled foraminifera; they appear in the fossil record during the Llandoverian epoch of the early Silurian. The earliest of these were microscopic, planispirally coiled, and evolute; later forms evolved a diversity of shapes including lenticular, globular, and perhaps most famously, elongated rice ... Brachiopod Fossils. The most common seashells at the beach today are bivalves: clams, oysters, scallops, and mussels. However, from the Cambrian to the Permian (542 to 252 million years ago), another group of organisms called brachiopods dominated the world's oceans. Over 12,000 fossil species of these hinge-valved organisms have been described ...Most fusulinids from the Hughes Creek Shale are well pre-served with clearly visible septal furrows on the spirotheca and a fluted antetheca (Fig. 1.1). Of the approximately nine hundred specimens of Hughes Creek fusulinids examined, however, about 20 percent have been damaged in one way or another. DamageThe Permian basin of west Texas and Southeastern New Mexico is one of the major petroleum producing regions of the United States. This basin produced 3% of the world's petroleum in 1984 and in that year, 1% of the world's proven reserves were in the Permian basin (Robichaud, 1989). Most of the Upper Permian hydrocarbon reservoirs are in San Andres and Grayburg formations (Galloway et al., 1983).An occurrence of Pennsylvanian upper Virgilian or lower Wolfcampian fusulinids is described in the northern Black Hills. Two additional fusulinid zones are reported from the southern Hills. In addition, two conodont faunas are described and illustrated.

One remarkable feature of the studied fusulinids is that their generic diversity, especially during the Sakmarian, was much lower than that of coeval fusulinids from tropical warm-water regions. Also, the dominant genera ...The fusulinids were cleaned by boiling them in Calgon® followed by ultrasonic cleaning for thirty minutes. They were then washed, sieved, and oven dried. Nine hundred fusulinids were inspected for evidence of encrustation, corrasion, compaction, and dissolution, the results of which are summarized in three graphs (Figs. 2-4).The main evolutionary trend in fusulinoidean morphology in the late Moscovian is the appearance of massive secondary deposits in the limestone of the "N" Formation. Specific temporal and ...The taxonomic determination of fusulinids at generic rank followed the scheme of Loeblich and Tappan (1987) and Sheng et al. (1988). To avoid over-splitting at the specific rank, we allowed wide ...The present fusulinids are assigned to the middle Kasimovian to early Gzhelian in age, representing the youngest fusulinid fauna in northern Xinjiang up to now, which constrains the age of the Qi'eshan Formation up to the early Gzhelian.

All test sections are determined to genus level, except for the genera Schubertella and Fusiella. Since it is impossible to distinguish between these two genera in oblique test sections, they are identified to the family Schubertellidae. The ...The fusulinids Beedeina and Wedekindellina appeared during widespread early Desmoinesian transgressions and characterized that interval. The mid-Desmoinesian extinction of Wedekindellina and turnover of Beedeina species coincided with a lowstand followed by a widespread transgression, generally higher sea levels, and changing paleoclimatic ...Samples between CE-75 and CE-76 are rich in small foraminifers and do not contain any fusulinids. The upper part of the Eskibey section is represented by a quartz sandstone level.

(cut surface; field of view ~2.9 centimeters across) This fossiliferous limestone is dominated by fusulinids, an extinct group of unicellular, marine benthic organisms. They had large, elongated, rice-like, microgranular, calcareous skeletons (tests) - they appear circular in transverse cross-section.Fusulinids referable to Millerella, Eoschubertella, Pseudostaffella, and Fusulinella are abundant throughout much of the formation. The term Youghall formation is proposed for the fossiliferous limestones, thin shales, and thick interbedded highly cross-bedded sandstones between the Hell's Canyon formation below and the Weber sandstone above. especially for fusulinids, which have been studied rarely, due to their traditional use primarily for biostratigraphy. The analysis of 900 well-preserved fusulinids, notably Tri-ticites ventricosus, indicates both biostratinomy and dia-genesis of the assemblage in the Hughes Creek Shale Mem-ber of the Foraker Limestone (Pennsylvanian, Virgilian) in The described fusulinids of the Moscovian Stage are found in the Asad-Abad section of the Sanandaj-Sirjan tectonic zone of Iran. Five successive fusulinid assemblages are distinguished. Three ...An endemic fusulinid assemblage is described from Sakmarian rocks of the Central Pamir. It consists of 42 species and subspecies belonging to the genera Pseudofusulina, Sphaeroschwagerina ...Fusulinids have also been considered a genus instead of an order in some classifications. They are some of the most complex forams. Fusulinids were omnivorous, eating via reticulopodia (cell extensions), which projected through pores in the test to catch small creatures. The shell is secreted by the protoplasm of the cell.Another peculiarity of this fusulinid bank is that all the shells are silicified: the silica has chemically replaced most of the calcium carbonate of which they ...The most abundant and widely distributed marine fossil records of Permian carbonate-dominated rocks in South China indicate a relatively stable shallow carbonate platform environment (Feng et al., 1996).Permian fusulinids were systematically classified and reported by Sheng, 1962, Sheng, 1963 and Sheng et al.
