Trachurus mediterraneus (Steindachner, 1868)

Figure 22h–k

Material 32 specimens, figured specimens SMF PO 101.239 , Dar bel Hamri, Zanclean .

Discussion Otoliths of T. mediterraneus differ from otoliths of T. trachurus in being slightly more compressed, showing a much stronger and finer crenulation of the dorsal and ventral rims and a more rounded postdorsal angle. Both species have been commonly recorded from Pliocene and Pleistocene sediments in the Mediterranean (e.g., Agiadi et al., 2019a).
