Material examined

IRAN – West Azerbaijan • 1 specimen; Aras Valley; Vedioceras Beds of the Julfa Formation ( late Wuchiapingian); 2011; Korn et al. leg.; illustrated in Fig. 44 View Fig ; MB.C.32071 .

Description

Specimen MB.C.32071 is a fragment of a juvenile specimen with a conch diameter of 35 mm ( Fig. 44A View Fig ). It shows a thickly pachyconic, involute conch (ww/dm =0.82; uw/dm=0.12) with a weakly depressed oval whorl profile (ww/wh= 1.43). The coiling rate is extraordinarily high (WER= 3.35).

Remarks

The specimen is too poorly preserved for a more detailed description. Because of the conch geometry and the extraordinarily high coiling rate, it probably belongs to Celeroliroceras gen. nov.
