M a t e r i a l. One trunk vertebra, EUNHM PV-13241, Nasrettinhoca 2, early Pliocene, MN 14; 20 vertebrae, EUNHM PV-13242–13261, Yenişarbademli, Middle Pleistocene.
D e s c r i p t i o n. All specimens are incomplete. The hypapophyses are broken off near their bases in each specimen. In ventral view, the centrum bears well-developed subcentral ridges. Small subcentral foraminae are located in both sides of the hypapophysis. The paradiapophyses are differentiated into parapophyseal and diapophyseal portions. The cotyle and condyle are relatively small and circular. The prezygapophyseal facet is longer than it is wide and horizontally oriented. The zygosphene is slightly crenate in dorsal view. The neural spines are usually damaged near their bases, but where partly preserved in a few specimens, they are relatively high. The neural arch is vaulted posteriorly.
R e m a r k s. The described vertebrae can be identified as Natricinae , Elapidae or Viperidae based on the presence of hypapophyses. The vaulted neural arch permits us to refer this vertebra to the Natricinae , but the relatively short centrum is not usual for these snakes.
