Figure 21e–f View Fig

Material 1 specimen SMF PO 101.232 , Dar bel Hamri, Zanclean .

Discussion Otoliths of D. hexophthalma are relatively thin, oval in shape with a ratio OL:OH of 1,25–1.4 (corrected from Schwarzhans, 1999) and a relatively thin sulcus. A recent specimen is figured for comparison

( Fig. 21e View Fig ). Te single fossil specimen from Morocco

( Fig. 21f View Fig ) resembles the extant specimens in all morphological aspects but is distinctly thicker (OH:OT = 2.7 vs. 3.5–4.5), and is, therefore, only tentatively placed in the same species.
