Biostratigraphy and paleontology of Catapsydrax, Globorotalia, Globigerinoita (planktic foraminifera) in the marine Miocene sequence of the Mut basin
Abstract
To reveal the planktic foraminifera biostratigraphy of the Köselerli formation in the Mut basin, 9 genus and 35 species of planktic foraminifera have been defined in the grain samples of measured sections. Genus and species of the foraminifera Catapsydrax, Globorotalia fohsi, Globigerinoita have been distinquished for the first time and defined as biozones. The base of the Miocene comprises terresterial facies, Catapsydrax dissimilis Zone defining the base of the marine Miocene. The intermediate level of Middle Miocene is defined by Globorotalia fohsi phyllozone (Globorotalia fohsi fosi, G. fohsi lobata, G. fohsi robusta) where the genus Globigerinoita is distinquished.

Abstract
Mut Havzas›, Köselerli Formasyonu’nun planktik foraminifer biyostratigrafisinin ortaya konmas›na yönelik olarak yap›lan bu çal›flmada, tane örneklerinin ölçülü kesitlerdeki tan›mlar› ile planktik foraminiferlerde 9 cins ve 35 tür saptanm›flt›r. Catapsydrax, Globorotalia fohsi, Globigerinoita planktik foraminifer cins ve türleri havzada ilk kez bu çal›flmada tan›mlanm›fl, biyozon olarak da ay›rtlanm›flt›r. Çal›flma alan›nda Miyosen’in taban› (Akitaniyen) karasal fasiyeste geliflmifl olup, Catapsydrax dissimilis Zonu (Geç Akitaniyen) ile denizel Miyosen’in taban› belirlenmifltir. Devam eden istif içerisinde Globorotalia fohsi Filozonu (Globorotalia fohsi fohsi, Globorotalia fohsi lobata, Globorotalia fohsi robusta) ile Orta Miyosen’in orta seviyesi belirlenmifl, bu zonlar da planktik foraminifer formlar› içerisinde stratigrafik olarak Globigerinoita cinsi de ay›rtlanarak tan›mlanm›flt›r.
