Material

Two otoliths from level 11.

Distribution

Lower Miocene of the Aquitanian Basin ( Steurbaut, 1984) and the MHB. Priabonian–lower Oligocene of SE France ( Nolf and Girone, 2008; Girone and Nolf, 2009).

Remarks

These otoliths are boat-shaped and have open, divided sulcus. The ostium is oval–rectangular and has an oval colliculum, whereas the cauda is oval-shaped, with an oval colliculum, and placed more dorsally than the ostium. There is a pronounced ventral fissure. These specimens have distinct posterior and posterodorsal angles that only appear on the otoliths of C. yrieuensis previously reported from the Rupelian of France ( Steurbaut, 1984). Compared to C. macrophthalma , these otoliths have an oval, rather than circular cauda, which is placed dorsally. Cepola aff. macrophthalma (Linnaeus) from the middle Miocene of Austria ( Nolf, 2013) also has an oval-shaped cauda but lacks a posterodorsal angle. On the contrary, this angle is present in C. robusta Nolf from the Ypresian of France ( Nolf, 2013), but only in the young specimens.
