Hatzegobatrachus grigorescui
Taxonomy
Hatzegobatrachus grigorescui was named by Venczel and Csiki (2003). Its type specimen is FGGUB v. 433, a limb element (A partial left ilium missing the distal part of iliac shaft and posterior margin of supraacetabular and subacetabular regions), and it is a 3D body fossil. Its type locality is Vălioara-Fântânele 1 (VF), which is in a Maastrichtian wet floodplain mudstone in the Densuş-Ciula Formation of Romania. It is the type species of Hatzegobatrachus.

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| M. Venczel and Z. Csiki 2003 | A small−sized anuran having an inferred snout-vent length of about 30 mm. Differs from Ascaphus, Leiopelma, Mesophryne, Notobatrachus, Prosalirus, pelobatoids, and some pipoids (Rhadinosteus), in having a well−developed dorsal protuberance of ilium. Differs from discoglossids (including Alytes, Callobatrachus, Discoglossus, Enneabatrachus, Eodiscoglossus, Latoglossus, Latonia, Paradiscoglossus, and Wealdenbatrachus), palaeobatrachids, and most pipids in the absence of an individualised dorsal iliac crest. Resembles Bombinatorinae in having a well−developed and undivided dorsal prominence, but differs from them in having its dorso−lateral margin more thickened. Differs from Bombinatorinae and Gobiatinae in the absence of any waisting between the acetabular region and the iliac shaft, resembling in this respect some leiopelmatid−grade anurans (Notobatrachus). Differs from rhinophrynids (including Chelomophrynus, Eorhinophrynus, and Rhinophrynus) in having comparatively smaller pre− and supraacetabular regions. |
