2023 Maeotichthys wilhelmi ( Djafarova, 2006) - Bratishko and Schwarzhans (in Bratishko et al., 2023; see there for further references): figure 4J–AA.

Material. Two specimens, SMF PO 101.338 , Jurkine, Kerch Peninsula, Crimea, microfauna sample #20, upper Vasylivkian , Bessarabian , middle Sarmatian s.l .

Discussion. Both specimens are fragmented, but one specimen could be reconstructed from the fragments retrieved and is shown digitally assembled in Figure 2E . Maeotichthys wilhelmi differs from the parallel occurring M. salebrosus n. sp. described below in the thinner appearance and the deeper ventral rim. Maeotichthys wilhelmi is widely distributed in the middle Sarmatian s.l. (Bessarabian) of the Eastern Paratethys and is also known from the early Sarmatian s.l. (Volhynian) of Bulgaria (Strashimirov, 1984, as revised in Bratishko et al., 2023).

FIGURE 2. Stratigraphic column of the Jurkine section with lithology, sedimentological observations, and fossil contents; lithostratigraphic levels are annotated (L 1 to L 20) as well as levels of microfauna samples (12 to 25 in circles); Oto-sample 1 and 2 indicate levels from which the studied otoliths were obtained for Bratishko et al. (2023). The otoliths studied here are from the microfauna samples 20 and 21. Key foraminiferal, ichthyological, and environmental changes are shown.
