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 ...The whorls of fusulinid foraminifera preserve a record of each individual's ontogeny, and therefore provide access to aspects of morphological life-history patterns. Outline-based morphometric analyses of representative fusulinid specimens assigned to Robustoschwagerina, Sphaeroschwagerina, and Schwagerina show that these genera exhibit ...A relatively complete succession of the Bashkirian to Moscovian rocks is exposed in the Hadim Nappe, central Taurides, where rich and diverse fusulinid assemblages have been analysed in three sections (Yassıpınar, Gölbelen and Bademli). The Bashkirian–Moscovian successions mainly consist of medium-bedded sandstones, medium–thick-bedded oolitic limestone and thin–medium bedded ...It looks like a weathered fusulinid.

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 ...Fusulinid faunas of the Pennsylvanian (Bashkirian-Moscovian) deposits of the Siyah Aladag Nappe were investigated from the Kuzuoluk section located in the eastern Taurides. The section is ...Fusulinid assemblages from the upper Pennsylvanian Gaptank Formation, the Wolfcampian Series (lower Permian), and the lower part of the Leonardian Series (lower middle Permian) include 50 species ...

The Guadalupian series includes two zones based on a sharp change of fusulinid genera, from Parafusulina to Polydiexodina. There are also some ammonoid zones and many sponges and algae. The Ochoa series has very few fossils, probably because conditions grew much less favorable for life during the last of the Permian, when many marine ...FUSULINID (FORAMINIFERIDA) FAUNAL REALMS TEXT-FIG. 3-Phylogeny of the families Schubertellidae and Fusulinidae and the distribution of genera in fusulinid biogeographic realms.

New fusulinid data from the Kolosseum locality, central Spitsbergen, show the process of fusulinid evolution in transitional Middle to Upper Carboniferous beds of the Arctic region. This well-preserved fusulinid fauna provides a clear understanding of the nature of Moscovian-Kasimovian fusulinid evolution; particularly in the Arctic region.They were benthic creatures that moved upon the sea-bottom muds, eating other tiny organisms. Fusulinids are abundant in Nebraska's late Paleozoic rock record. They become extinct at the end of the Permian. This is a rock consisting of many fusulinids.
