Genus Natrix Laurenti, 1768

Natrix sp.

( Fig. 2 /8)

Only a trunk vertebra can be classified as that of a snake. The trunk vertebra, which could be studied dorsally and posteriorly, is small in size, the length of the centrum is about 4 mm. The neural spine is relatively thin. The zygosphene is straight, provided with two lateral tubercles. The hypapophysis is posteriorly more prominent, expanding to the anterior verge of the condyle. The appearance of this vertebra is similar to those of the living Natrix natrix (e.g. ČERŇANSKÝ 2011, Fig. 8M-R) but the largest part of this bone cannot be studied.
