Discussion Otoliths of D. quadrimaculatus have frequently been retrieved from Pliocene rocks from Mediterranean realms. Tey are easily distinguishable from D. planus by the more elongate shape in adults (OL:OH = 1.15), while small specimens at a size of about 1.05 are similar in proportions (see extant specimen in Fig. 19d View Fig and small fossil specimen in 19 k). Te sulcus is larger in D. quadrimaculatus than in D. planus , with a weaker asymmetry of the ostium to cauda, and the inner face is distinctly convex.
