Jun 1, 2022 · The fusulinid assemblage is characterized by the dominance of staffellids that shows a different composition from the other late Moscovian fusulinid faunas reported in South China. Combined with microfacies analysis, we suggest that the different faunal composition most likely resulted from varying depositional settings, implying the ...

Oct 16, 2023 · To meet different research needs, multiple sections of fusulinid fossils, including axial, sagittal and tangential sections, could be produced, and axial sections are preferred for identification as they contain the most useful features (Sheng et al., 1988; Vachard et al., 2010). This slice-based identification of fusulinids is very beneficial ... Fossil classification is the cornerstone of paleontology, and the proper determination of fusulinid species is vital to cor- relate Permo-Carboniferous strata, and to reconstruct Pa-Guide to Fossil Classification. Table 0.1 summarizes the kingdoms in the Linnaean classification system that we will follow for this course. Most of the groups we will be examining are part of Kingdom Animalia, but there are a few exceptions.

Agglutinated Foraminifera remained the dominant group in the Lower Palaeozoic but a spectacular increase in number and kinds of Foraminifera occurred in the Upper Palaeozoic with the rise of the calcareous microgranular group. With the advent of wholly secreted tests, Foraminifera became important contributors to limestones ... of late Permian time, nearly all fusulinids became extinct, except in the Eurasian Tethyan seas where advanced members of the Schubertellidae and Staffellidae formed a distinctive associa-tion in the youngest fusulinid faunas.
