Figure 6 View FIGURE 6 A-B

Material. 2 otoliths, NMNHU-P PI 2707, Staryi Zavod.

Discussion. Two small otoliths just below 1 mm in length are interpreted to represent an unspecified gasterosteid species indicating a rare freshwater influence in the Medobory backreef. These two small otoliths ressemble Pungitius kornyensis (Schubert, 1902) as figured in Schwarzhans (2017), which is known from the Karaganian of Bulgaria, in the overall otolith shape and the narrow slightly undulating sulcus with its small ostium. The otoliths are characterised by a regular oval outline with a moderately protruding rostrum and a narrow, slightly flexed sulcus with long cauda and short, minimally widened ostium.
