Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| A. Osi 2005 | Armored dinosaur, approximately 4 m long; large notch at front of premaxillae, thin nasal process of premaxillae, robust rhomboidal quadrate condyles, large interpterygoid vacuity, dorsoventrally wide quadratojugal with strong protuberance, posterodorsally oriented crest-like protuberance on postorbital, short diastema between symphysis and first dentary tooth position, very short retroarticular process of surangular, anteriormost dorsal vertebra with unusual transversely wide, anteroposteriorly short amphycoelous centrum, with very large neural canal, dorsally displaced pseudoacromial process of scapula. | |
| A. Osi and L. A. Makádi 2009 | Armored dinosaur, estimated body length 4 m. Differs from all other known ankylosaurs in having a postorbital bearing a high and anterodorsally–posteroventrally elongated crest, a thin, rod-like, dorsoventrally flat jugal, a large, inverted U-shaped premaxillary notch that is as high dorsoventrally as wide mediolaterally, a forelimb–hindlimb length ratio of 1.0 (humerus/femur = 0.92).
Hungarosaurus is distinguished from the other European Late Cretaceous ankylosaur, Struthiosaurus, by the following characters: the dorsoventrally wide quadratojugal ornamented by a large, rounded protuberance laterally, mandibular quadrate condyle being more robust with rhomboidal articular surface, presence of interpterygoid vacuity, postacetabular process comprising approximately 38% of the total ilium length. |
