Bakonybatrachus fedori

This species belongs to the oldest frog group (Archaeobatrachia) and within that to the family of discoglossid frogs (Discoglossidae), the members of which have lived from the Middle-Jurassic to the present. The species was first described on the basis of the ilium, which is relatively thin, but the high iliac crest is unique in the family. This high iliac crest was probably attached to powerful muscles, so the Bakonybatrachus must have been much better at swimming and jumping than the currently living representatives of the family. Based on the animal’s body structure and the condition of the remaining bones, it can be concluded that it probably lived in the floodplain lakes or backwaters of the area.
