Salamandra spec.

Description. The vertebrae are opistocoelous and dorsoventrally flattened. They are large in size (5 - 7 mm). In dorsal view, the neural arch is broad and has an outline of a rectangle (HLMD-Ez 2029, Fig. 5 A) or square (HLMD-Ez 2031, Fig. 5 F). The prezygapophyses have round outlines and project anterolaterally. The neural arch between the prezygapophysese is flat. The neural spine starts behind this short flat surface and posteriorly does not reach the posterior tip of the pterygapophysis. In lateral view, the neural spine is low. It is highest at its middle point. The posterior margin of the pterygapophysis can be bifurcated. Its posterior surface possesses two distinct notches of variable sizes and dimensions. In anterior view, the neural canal is dorsoventrally flattened. In HLMD-Ez 2029, the bases of the prezygapophyses are pierced by the subzygapophyseal (sensu Vasilyan et al. 2017) or anterior (sensu Tissier et al. 2015) foramen. Other vertebrae do not have this character. The arterial canal with large and / or smaller openings runs across the base of the transverse process. The latter is fully preserved only in HLMD-Ez 2029. It projects posterolaterally and is composed of dia- and parapophysis, which are connected with a thin lamina at their medial half (Fig. 5 B); otherwise, they are free laterally. Additionally, the parapophysis is connected with the centrum anteriorly and posteriorly by anterior and posterior alar processes, respectively. They build a triangular-shaped lamina (Fig. 5 C). In lateral view, a well-pronounced horizontal interzygapophyseal ridge connects the prezygapophysis with diapophysis, whereas the horizontal dorsal lamina connects the diapophysis with postzygapophysis. The centrum is flattened dorsoventrally and arched.
