Phonetic: Hun-gar-o-sore-us.
Named By: A.‭ ‬Osi‭ ‬-‭ ‬2005.
Classification: Chordata,‭ ‬Reptilia,‭ ‬Dinosauria,‭ ‬Ornithischia,‭ ‬Ankylosauria,‭ ‬Nodosauridae.
Species: H.‭ ‬tormai‭ (‬type‭)‬.
Diet: Herbivore.

Known locations: Hungary-‭ ‬Csehbanya Formation.
Time period: Santonian of the Cretaceous.
Fossil representation: Collected remains of‭ ‬4‭ ‬individuals.

       Several hundred bones from an estimated four individuals have been attributed to this genus,‭ ‬and together they make up the best represented European genus of nodosaurid dinosaur.‭ ‬Like its nodosaurid relatives,‭ ‬Hungarosaurus was an armoured quadrupedal dinosaur that would have browsed upon low growing vegetation.‭ ‬The armour would have been an arrangement of bony plates called osteoderms‭ (‬also called scutes‭) ‬that would have connected together to form a tough covering across the back and flanks of the body.‭ ‬As a nodosaurid however,‭ ‬Hungarosaurus probably lacked a bony club on the end of it tail,‭ ‬which is‭ ‬a‭ ‬common feature seen in ankylosaurids,‭ ‬another group of armoured dinosaurs very closely related‭ (‬and probably descended from‭) ‬to the nodosaurids.‭
       Study of the fossil bearing formation that Hungarosaurus has been discovered in indicates that this genus lived in a low lying floodplain,‭ ‬an area where the rich fertile soil would allow for the growth of a readily available supply of low growing vegetation.‭ ‬The fact that the remains of four individuals were found close together may indicate that Hungarosaurus,‭ ‬and possibly other nodosaurids,‭ ‬lived in groups.‭ ‬An alternative is that the four may have drowned and been washed together during a flood,‭ ‬something quite likely given the floodplain ecosystem where they seem to have lived,‭ ‬however this does not adequately disprove the group living theory in its entirety.
