Abstract

The Aladag Mountains at the western end of the eastern Taurides, southern Turkey, are composed of nappe structures imbricated in the Late Cretaceous by ophiolite emplacement. The Cataloturan Nappe contains Mississippian (i.e., Early Carboniferous) deep-water (basinal-lower slope) facies in the lower part and shallow-water (shelf edge) facies in the upper part. These Mississippian strata belong to the Nohutluk Formation. The main outcrop occurs at Nohutluktepe where it is 460 m thick. Eighty taxa of algae, foraminifers, and calcareous microproblematica permit dividing the upper part of the formation into three informal assemblage biozones: (1) Howchinia bradyana longa - Lituotubella magna - Koktjubina (?) sp. biozone (late Viséan Cf6γ1), (2) Bradyina rotula - Euxinita tauridiana biozone (Cf6γ2), (3) Janischewskina typica - Biseriella aff. parva biozone (upper Cf6δ). The genus Euxinita is discussed and a new species E. tauridiana nov. sp. is described. A paleobiogeography, based on Euxinita, Koktjubina (?), Vissarionovella, Janischewskina and Hortonella, is reconstructed, where the Taurides are juxtaposed to the northwestern border of the Paleotethys, with possible direct connections with Russia, Kazakhstan, western Europe, and Morocco. © 2006 Elsevier SAS.
