Fusilinids
The Fusulinidae is a family of fusulinacean foraminifera from the upper Carboniferous (Lower Pennsylvanian, Morrowan) to the Upper Permian ( Guadalupian ), tests of which are fusiform to subcylindrical with walls of two to four layers. Are planispirally coiled throughout or with early whorls at a distinct angle to the later plane of coiling. The Schubertellids underwent slower evolutionary morphological change than earlier fusulinids and were decreasingly dominant through the Permian. A similar pattern of fusulinid evolution and extinction at the Guadalupian-Lopingian boundary occurs in shallow-water Tethyan shelf areas and mid-oceanic shallow-water environments in mid-Panthalassa. The 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 elongated rice-shaped forms.

The traditional methods to examine their internal structures are through ground thin sections, which however caused lots of ambiguities regarding the morphological diagnostics and taxonomic identification.Leven EJ, Scherbovich S (1978) Fusulinids and Asselian stratigraphy of Darvas.

I'm not seeing fusulinids. I do see brachiopods, coral, bryozoa, crinoid, and maybe clams. Those are very nice finds!
