Iharkutosuchus ("Iharkút crocodile", after where it was found) is an
extinct genus of
basal eusuchian crocodyliform. It fossils have been found in the
Santonian-age
Upper Cretaceous Csehbánya Formation in the
Bakony Mountains of western
Hungary. 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 , estimated body length ). 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. The genus was described in 2007 by Attila Osi and colleagues. The
type species is
I. makadii, for László Makádi.
