genus C

New genus C Korn & Hairapetian (in press) sp. Fig. 33; Table 19 Material examined IRAN – East Azerbaijan • 1 specimen; Zal; Zal Member of the Ali Bashi Formation (early Changhsingian); 2018; Ghaderi leg.; illustrated in Fig. 33; MB.C.32059. Description Specimen MB.C.32059 is a fragment of a conch with a diameter of about 125 mm (Fig. 33A). It is vertically distorted and only allows the study from one side; the conch dimensions and ratio can only be estimated. It bears a coarse sculpture consisting of eleven rounded ribs on half a volution. These ribs extend with a concave sinus across the flank; they are particularly strongly developed in the ventrolateral region. Remarks The single fragmentary specimen does not provide sufficient data for a clear characterisation. It is thus kept in open nomenclature.
