| Abstract |
In Northwestern Turkey, the Mississippian (Lower Carboniferous) Yılanlı Formation is composed of variegated shallow- water limestone containing rugose corals, tabulate corals and brachiopods. Six sections were sampled in the Zonguldak and Bartın areas, from east to west, there are Süzek, Topluca, Gökgöl, Kokaksu, Ulutam and Kisla sections. Among the rugose corals, a rich and diversified assemblage of Lithostrotionidae has been collected. The latter contains the species: Nemistium cf. affine, Siphonodendron ondulosum, S. martini, S. irregulare, S. pauciradiale, S. asiaticum, S. rallii sp. nov., S. scaleberense, S. kleffense, S. aff. kleffense, Lithostrotion araneum, L. vorticale, L. sp. and L. potii sp. nov. During the Moliniacian it is proposed that subcerioid colonies of S. ondulosum gave rise to cerioid colonies of Lithostrotion potii sp. nov., the latter constituting the oldest species of the genus previously considered to be Livian to Warnantian in age. This discovery led to an emendation of the phyletic lineage of the Lithostrotionidae. The biostratigraphy based on rugose corals indicates a Moliniacian (early Viséan) and Warnantian (late Viséan) age of the deposits with the absence of the intervening Livian (middle Viséan). |
