Studies of Mesozoic amphibians
Taxonomical, functional anatomical, palaeoecological and palaeobiogeographical studies of Mesozoic amphibians (Lissamphibia)
The evolution of lissamphibians is still unknown mostly because there are relatively few findings, which are mainly fragmentary. In addition, the gaps between the records are large. This is especially true for the Mesozoic era and within that for the Late Cretaceous, from which The European amphibian material is studied by Zoltán Szentesi. Until the discovery of the Santonian (ca. 85 MA) Iharkút vertebrate locality, there had not been any amphibian records found in Europe from the Cenomanian up to the Campanian period (ca. 99-83.5 MA). So, the microvertebrate record of Iharkút can provide useful information on the evolutionary events of Lissamphibians.
The radiation of Lissamphibians, which took place in the Mesozoic, is also an important question for many researchers. It is still unknown when and where exactly the groups of these amphibians were originated and in what ways they radiated and were distributed to their present habitats.
The complete examination of the Iharkutian Late Creataceous amphibian fauna is aimed at, which, besides taxonomical studies, includes the palaeobiological, palaeoecological and taphonomical investigations as well as the study of the palaeobiogeographical radiation of the unearthed taxa from this locality. The research involves the study of lissamphibian faunas of other Late Cretaceous European localities and in some cases (e.g. Chera and La Solana, Spain) the examination of those unearthed findings as well. This has been the first work on Mesozoic amphibians in Hungary.
