İstinye Formasyonu’nun (Yumrukaya grubu) Beykoz ve Karamandere kesitlerinden delta-pesavis zonlarını (üst Lohkoviyen, Alt Devoniyen); Kartal Formasyonu’nun Kozyatağı üyesinin Büyükdere ve Kokarpınar (İstanbul) kesitlerinden ise laticostatus, serotinus, patulus ve partitus zonlarını (üst Emsiyenalt Eyfeliyen, Alt-Orta Devoniyen) tanımlayan konodont faunaları elde edilmiştir. Neopanderodus (2), Icriodus (8), Pelekysgnathus (1), Lanea (1), Polygnathus (4), Ozarkodina (2), Pseudooneotodus (2), Belodella (2) cinslerine ait toplam 22 tür/alt tür tanımlanmıştır.

Conodont fauna and biostratigraphy of the Early-Middle devonian units in Beykoz, Şile and Kurtdoğmuş areas, Istanbul, Turkey

The conodont faunas defi ning the delta-pesavis zones (upper Lochkovian, Lower Devonian) were obtained from Beykoz and Karamandere sections of the İstinye Formation (the Yumrukaya group) and the conodont faunas of the laticostatus, serotinus, patulus and partitus zones (upper Emsian-lower Eifelian, Lower-Middle Devonian) were obtained from the Büyükdere and Kokarpınar sections of the Kozyatağı member of the Kartal Formation. A total of 22 species/subspecies were described belonging to the genera Neopanderodus (2), Icriodus (8), Pelekysgnathus (1), Lanea (1), Polygnathus (4), Ozarkodina (2), Pseudooneotodus (2), Belodella (2).
