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.
Description
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 {{convert|11.1|cm|in}}, estimated body length {{convert|0.8|m|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.{{cite journal |last=Ősi |first=Attila |author2=Clark, James M. |author3= Weishampel, David B. |year=2007 |title=First report on a new eusuchian crocodyliform with multicusped teeth from the Upper Cretaceous (Santonian) of Hungary |journal=Neues Jahrbuch für Geologie und Paläontologie, Abhandlungen |volume=243 |issue=2 |pages=169–177 |doi=10.1127/0077-7749/2007/0243-0169}}{{cite journal |last=Ősi |first=Attila |author2=Weishampel, David B. |year=2009 |title=Jaw mechanism and dental function in the Late Cretaceous basal eusuchian Iharkutosuchus |journal=Journal of Morphology |volume=270 |issue=8 |pages=903–920 |doi=10.1002/jmor.10726 |pmid=19206154 |doi-access=free }}
Classification
The genus was described in 2007 by Attila Ősi and colleagues. The type species is I. makadii, named for László Makádi. A 2011 phylogenetic study recovered Iharkutosuchus as a member of Hylaeochampsidae, a group of basal eusuchians, as shown in the cladogram below.{{cite journal |last=Buscalioni |first=A.D. |author2=Piras, P. |author3=Vullo, R. |author4=Signore, M. |author5= Barbera, C. |year=2011 |title=Early eusuchia crocodylomorpha from the vertebrate-rich Plattenkalk of Pietraroia (Lower Albian, southern Apennines, Italy) |journal=Zoological Journal of the Linnean Society |volume=163 |pages=S199–S227 |doi=10.1111/j.1096-3642.2011.00718.x |doi-access=free }}
