Material.
Three ilia HLMD-Ez 2092-2094.
Description.
The best-preserved ilium (HLMD-Ez 2094, Fig. 9G, H View Figure 9 ) shows a well-developed (rather narrow and high) dorsal acetabular expansion and a reduced (broad and low) ventral acetabular expansion. The dorsal prominence is not very high. It is oriented rather anteriorly than anterodorsally. The dorsal protuberance has an oval outline. Its surface is either smooth (HLMD-Ez 2094, Fig. 9G View Figure 9 ) or possesses muscle scars (HLMD-Ez 2093, Fig. 9E View Figure 9 ). The iliac shaft is rather thin and round in cross-section. A low and thin bone lamina connects the iliac shaft and the dorsal prominence. In posterior view, the dorsal prominence projects laterodorsally. The ilioischiatic juncture is narrow (Fig. 9H View Figure 9 ).
Remarks.
Echzell frog ilia can be clearly assigned to green Pelophylax and brown Rana frogs based on the following characters. The genus Pelophylax is characterised by: anterodorsally oriented, high, large and dorsomedially curved dorsal prominence and protuberance; the dorsal protuberance has a smooth surface; whereas the genus Rana by in lateral view anterodorsally and in posterior view laterodorsally oriented, rather low and reduced dorsal prominence and protuberance, the dorsal protuberance has smooth or irregular surface ( Böhme 1977; Blain et al. 2007).
