| Abstract |
The Köprülü Formation of the Hakkari area (SE Turkey) is composed of a mixed carbonate–siliciclastic succession of Early Carboniferous age. The lower part of the formation yielded an abundant but poorly diversified coral fauna composed of small non-dissepimented solitary rugose corals, namely Rotiphyllum cf. simulatum Fedorowski 2009, Zaphrentites parallela (Carruthers, 1910), cf. Gorizdronia, gen. et sp. indet., Amplexizaphrentis sp. and Amplexizaphrentis zapense sp. nov. and specimens of Caninia cf. cornucopiae Michelin in Gervais 1840, a dissepimented solitary coral showing a counter septum-related columella. The lower part of the Köprülü Formation is of supposed late Tournaisian age based on micropaleontological data. However, the coral assemblage indicates rather an early Viséan age. The Hakkari corals form a strongly facies-related association (“Cyathaxonia fauna”) and are compared to other areas with some difficulties. The most similar, time-equivalent faunal associations is that of the Sinai Peninsula (NE Egypt). Both localities belonged, during Early Carboniferous times, to the Arabian Platform situated along the northern margin of Gondwana. The Gondwana-related Taurides units (Aladag), North Iran Block and Afghanistan, characterized by a dominant carbonate facies and more diversified coral faunas, formed during these times, the distal parts of the Arabian Platform. |
