Schizogony in Orbitoides Apiculatus Schlumberger from the Maastrichtian of Şereflikoçhisar (Central Anatolia-Turkey)

Abstract: In this study, a microspheric individual of Orbitoides apiculatus Schlumberger having a large number of megalospheric embryos near the both peripheries of the test fossilised in the period of schizogony from the Asmaboğazı Formation outcropping around the north of the Asmayaylası Village (Southeast of Şereflikoçhisar-Central Anatolia) is described. The individual including 22 megalospheric embryos in different positions also brings out existence of schizogonic type reproduction in rich orbitoidal foraminifera community indicating shallow water paleoenvironments as seen in the examples o/Orbitoidcs species in various regions of Turkey.
