Sažetak

Oligocene (Rupelian-early Chattian) new larger benthic foraminiferal taxons such as miliolid genus Sivasina n. gen., SİREL & ÖZGEN-ERDEM (type species Sivasina egribucakensis n. gen. n. sp.SİREL & ÖZGEN-ERDEM) occurs in the Eğribucak, Bakımlı, Tuzlagözü and Çaygören sections (E of Sivas). One new Rupelian-early Chattian lagoonal-shallowest-water peneroplid species Peneroplis flabelliformis n. sp., SİREL & ÖZGEN-ERDEM from the Eğribucak, Tuzlagözü and Çaygören sections and Rupelian lagoonal two new peneroplid species Coscinospira sivasensis n. sp. SİREL & ÖZGEN-ERDEM, Coscinospira elongata n. sp. SİREL & ÖZGEN-ERDEM from the Eğribucak section (E of Sivas), two new Rupelian shallowest-water alveolinid species Praebullalveolina oligocenica n. sp. SİREL & ÖZGEN-ERDEM and Praebullalveolina minuta n. sp. SİREL & ÖZGEN-ERDEM from the Bakımlı section are described and figured. Furthermore, the description of the known Oligocene soritid species Praearchaias diyarbakirensis SİREL, Praearchaias minimus SİREL, Archaias kirkukensis HENSON, Archaias asmaricus SMOUT & EAMES, peneroplid species P. cf. laevigatus d’ ORBIGNY and austrotrillinid species Austrotrillina brunni MARIE are given shortly. In addition, the biostratigraphy of four studied sections are introduced.
