2020a Knipowitschia polonica —Schwarzhans, Brzobohatý & Radwańska: pl. 9, figs. 15–18 (and references therein).

Material 5 otoliths: 1 specimen, Kozatskyi Yar, NMB P1213; 1 specimen, Mlyntsi, NMNHU-P PI 2561; 3 specimens, Shydlivshchyna, NMNHU-P PI 2562.

Discussion Te otoliths of this species can be recognized by the high-bodied shape (OL:OH = 1.0–1.1), the pointed preventral and postdorsal projections, and the small, narrow sulcus with low ostial lobe and narrow, often indistinct subcaudal iugum. Knipowitschia polonica has been found to be relatively common in the early Badenian of Korytnica, Poland ( Schwarzhans et al., 2020a), but this is the first record of this species in the late Badenian.
