A section near the Kilgen Lake (Adana Province) has yielded a fauna of rugose and tabulate corals including Disphyllum cf. rugosum (Wedekind, 1922), D. cf. curtum Hill, 1954, Wapitiphyllum sp., Thamnopora n. sp. and Alveolites sp. This coral assemblage is consistent with the previous Frasnian age assigned to the limestones of the Gümüşali Formation. The rather well preserved material provides new data on the structure and microstructure of Disphyllum and allows to describe in Thamnopora unusual calicinal morphology (septal ridges, median teeth, pseudopercula) as well as new structures linked to the lateral increase (basal low wall, apical cul-de-sac).
