Fusilinids.

In some porcelaneous species, small depressions in the surface ornamentation give the appearance of pores. Another type of wall structure, called microgranular, is made of tightly packed equidimensional rounded grains of calcite. This wall type is found in many Paleozoic foraminifera including the fusulinids. Figures 1-6.Silica Fabrics / Fossils: Small fusilinids and colonies of calcarious algae. In variation #6 and #7 abundant fusilinids and small brachiopods are present.
