Material 1 otolith, Shydlivshchyna, NMNHU-P PI 2557. Discussion Te single, large otolith of 3.3 mm in length is readily recognized by the slightly convex inner face and the flat outer face, the parallelogram-like shape, and the postdorsal projection being markedly bent outward. Te sulcus shows a shoe sole shape with moderate ostial lobe, and the subcaudal iugum is clearly discernable despite erosion. Gobius reichenbacherae was a common and widespread species in the middle Miocene of the Mediterranean and Paratethys and the late Miocene of the Mediterranean ( Schwarzhans et al., 2020a , 2020b ).
