The Iharkút lissamphibian assamblage consists of a mixture of autochthonous Laurasian taxa
[albanerpetontid allocaudatans, discoglossid (Bakonybatrachus) and pelobatid anurans] along
with those of Gondwanan origin (the neobatrachian Hungarobatrachus). Functional anatomical
interpretations of the preserved iliac structures and taphonomical observations were used in the
reconstruction of the paleoecological conditions. Different paleoecological circumstances of
these groups are indicated by the attachment surfaces of locomotory muscles in the preserved
iliac bones of Bakonybatrachus and Hungarobatrachus and compared to recent representatives
of discoglossid and ranid frogs (i.e. Discoglossus and Rana). Large insertion surfaces for m.
gluteus maximus and for the m. iliacus externus pars externa indicates that Bakonybatrachus
had good jumping and swimming abilities pointing to a periaquatic life-style, whereas the large
m. iliacus externus and m. ilifibularis-iliofemoralis combined with a huge interiliac tubercle,
suggest that Hungarobatrachus was a strong jumper, swimmer or both
