84 Anurans and squamates from the Lower Pliocene (MN 14) Osztramos 1 locality The vertebrae are of small size. The ventral surface of of the osteoderms is covered with vermicular shaped the centrum is flattened; in ventral view the lateral tubercles. The remains of Anguis are abundant in the margins of the centrum are parallel. The dorsal surface Late Neogene European localities. Genus Pseudopus MERREM, 1870 Pseudopus pannonicus (KORMOS, 1911) (Figure 3: E-H) Material — Osztramos 1/b: 1 osteoderm, 1 trunk vertebra, 1 dentary (HNHM. No. V.99.20); Osztramos 1 /c: 1 frontal, 1 caudal vertebra, 1 osteoderm (HNHM. No. V.99.21). Description and comments — The morphology of the frontal does not differ significandy from that figured by FEJÉRVÁRY-LÁNGH (1923, Plate 1, Fig. 2a). The teeth in the dentary are conical with their tips broken off; the posterior ones are extremely reduced in Figure 5 — Eryx sp. (A-E), Coluber hungaricus (F-I) and Coronella cf. austriaca (J-M) from Osztramos 1. — A, B: anterior trunk vertebra (Ol/e, No.); C, D: trunk vertebra (Ol/e), E: caudal vertebra (Ol/e); F, G: quadrate (Ol/b); H, I: trunk vertebra (Ol/c); J, K: quadrate (Ol/b); L, M: trunk vertebra (Ol /b). — A, C, I, M: dorsal views; B, L: lateral views; D, H: ventral views; E: anterior view; F, J: posterolateral views; G, K posterior views. height. The few vertebrae preserved are of relatively small size. The centrum is short, the ventral surface is flattened, and somewhat triangle-shaped. The condyle is rather distinct. The posterior part of the outer surface of the osteoderms is covered with vermicular-shaped tubercles, while the anterior part is smooth. During the Late Neogene Pseudopus pannonicus was widely distributed in Central Europe, even in northern areas such as Poland (MLYNARSKJ et. al. 1984). Figure 6 — Elaphe kormosi (A-D), Elaphe sp. (E, F) and E. praelongissima (G—K) from Osztramos 1. — A: supraoccipital (Ol/c), B-D: trunk vertebra (Ol/c), E, F: basiparasphenoid (Ol/e), G: prootic (Ol/b), H: exoccipital (Ol/b), I-K: trunk vertebra (Ol/c). — A, B, F, I: dorsal views; Q G, FT, J: lateral views; D, E, K ventral views.
