Pelophylax sp.
Fig. 9A-D
Material.
Four ilia HLMD-Ez 2088-2091.
Description.
All ilia are fragmentary. The iliac shaft and most proximal portions are missing. The dorsal prominence is well developed; it is high, in lateral view projects anterodorsally, whereas in posterior view, it has a medially curved outline. The dorsal protuberance is massive, drop-shaped, with a rounded surface (Fig.
9D
). The supraacetabular fossa is moderately developed and located posteriorly from the ventral base of the dorsal prominence. The acetabular ridge is ventrally significantly higher than dorsally (Fig.
9C, D
). The iliac shaft is rather thin and round in cross-section. The iliac shaft and the dorsal prominence are connected by a high and thin bone lamina.
