Extinct genus of reptiles From Wikipedia, the free encyclopedia
Iharkutosuchus ("Iharkút crocodile", after where it was found) is an extinct genus of basal eusuchian crocodyliform. Its fossils have been found in the Santonian-age Upper Cretaceous Csehbánya Formation in the Bakony Mountains of western Hungary.[2]

It is based on MTM 2006.52.1, a nearly complete skull, and several other partial skulls, isolated skull bones, and numerous teeth are also known. Iharkutosuchus was a small crocodyliform (skull length 11.1 centimetres (4.4 in), estimated body length 0.8 metres (2.6 ft)). Its skull was low, and the snout was short. Iharkutosuchus is unusual in its heterodonty: some of its teeth were complex and multicusped, like mammal teeth. The structure of the skull indicates that it could grind food with a mobile lower jaw, and together with the teeth suggest a diet of fibrous plant material.[2][3]
The genus was described in 2007 by Attila Ősi and colleagues. The type species is I. makadii, named for László Makádi.[2] A 2011 phylogenetic study recovered Iharkutosuchus as a member of Hylaeochampsidae, a group of basal eusuchians, as shown in the cladogram below.[4]
