Alibashinautilus undetermined

Alibashinautilus sp. Fig. 29 Material examined IRAN – West Azerbaijan • 1 specimen; Aras Valley; Araxoceras Beds of the Julfa Formation (early Wuchiapingian); 2018; Ghaderi leg.; illustrated in Fig. 29; MB.C.32056. Description Specimen MB.C.32056 is a body chamber fragment (Fig. 29A) with a whorl height of 30 mm and a whorl width of 26 mm. The whorl profile is almost perfectly oval and is only influenced by a very small whorl overlap zone (Fig. 29B). The specimen shows quite coarse and broadly rounded, straight ribs on the flank. Remarks The single specimen most probably represents an own, independent species, but its fragmentary preservation does not provide sufficient data for a clear characterisation. It is thus kept in open nomenclature.
