During the Permian period, the variation in species, individual sizes, and morphological characteristics of the different assemblages, such as the fusulinids, is a clue to paleoecological and paleoenvironmental interpretations.

Internally, there is a winding narrow coil of protoplasm called a columella that is formed by the chamber septa that meet at the shell pores. Interestingly, fusiform lineages have arisen twice in the history of lf: the fusulinids in the Pennsylvanian (they became extinct at the end of the Paleozoic) and the Cretaceous–Cenozoic aveolinids.Permian fusilinids from the Penchi.

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

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.
