Extra details from original publication
Remarks.– Koutsoukosia differs from all other triserial genera of the Cretaceous by having the test ornamentation consisting of blunt pustules (Fig. 2; Pl. 1, Fig. 2). The pore mounds mentioned in the original description of the type species are probably the result of diagenesis, which affected the original ornamentation on the chamber surface. Overall, the ornamentation of Koutsoukosia is similar to that of the primitive planktic foraminifera of the Family Globuligerinidae (Riegraf, 1987; Simmons et al., 1997).
