“ Gobius ” aff. weileri Bauza Rullan, 1955

This single thickset otolith is characterised by a rectangular shape and an elliptic sulcus, filled completely by an undivided colliculum ( Fig. 11N ). The sulcus margins are thick and swollen, and a slight constriction is observed at the middle of both anterior and posterior rims of the otolith. It is more similar to specimens from the lower Pleistocene deposits of northern Italy figured by Nolf & Girone (2000: pl. 3, figs 15–16) than to the one from the lower Pliocene deposit figured by Nolf & Cavallo (1995: pl. 8, fig. 10), but the thickness of our specimen resembles more the latter.
