Order SILURIFORMES Cuvier, 1817

Family SILURIDAE Cuvier, 1816 Genus Silurus Linnaeus, 1758

Silurus glanis Linnaeus, 1758 — one fragment of keratohyale (Nik 11 – 1/5, fig. 4, 1 ), one vertebra without apophyses (Nik 11 – 1/6, fig. 4, 2 ). Measurements of these remnants are the following: L keratohyale = 6.4 cm, W keratohyale = 1.6 cm; diameter of vertebra is 2.1 cm. It is morphologically similar to those in the European catfish, except the robustness and size. Fossil remnants of Silurus and Parasilurus are known from the Pliocene deposits of Grebeniki ( Pozdnyakov et al., 1992), Priozernoe in the RM, and also were identified in materials from the south of Ukraine ( Tarashchuk, 1962).
