kraffti, which is unusual among the known late Early Permian fusulinid faunas from the eastern Cimmerian continent. In contrast, a number of late Artinskian-early Kungurian fusulinid faunas were known in the eastern Cimmerian blocks, but they have less faunal linkage to the paleo-tropical Tethyan region (Ueno et al., 2015).Abstract: A review of Permian fusuline biostratigraphy is made in this paper in order to improve the correlation of Permian strata globally. Permian fusuline biostratigraphy in the Tethyan and Panthalassan regions can be correlated roughly because the fusulines had good faunal communications between these two regions.Abstract. 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 ...
