Hungarosaurus is a genus of pelvic dinosaur from the group of Ankylosauria . Remains of this dinosaur werediscoveredin Hungary at the beginning of the 21st centuryand are exhibited in the Hungarian Natural Science Museum in Budapest.
features
Hungarosaurus reached an estimated length of around 4 meters. As with all ankylosauria, the neck and back were protected with armor made of bone plates (osteoderms). Two rows of plates ran along the neck, the back was covered with oval or diamond-shaped structures. There were also spines in the area of the pelvis . As in all ankylosauria, the limbs were short, the trunk stocky. Like all representatives of this group, Hungarosaurus moved quadruped .
The skull is known so far only of fragments, its length is estimated at 26 to 32 centimeters. It was comparatively elongated and relatively large. The teeth were small and leaf-shaped and adapted to a vegetable diet.
Discovery and naming
The fossil remains of four individuals of Hungarosaurus were discovered. The finds come from a bauxite mine in the Hungarian Bakony Forest and were first described by Attila Ősi in 2005. The type and only known species is Hungarosaurus tormai . It is the best preserved ankylosaur from the Upper Cretaceous Europe. The finds are dated in the Upper Cretaceous ( Santonium ) to an age of around 86 to 84 million years.
Systematics
Hungarosaurus is classified within the Ankylosauria as a basic representative of the Nodosauridae . With Struthiosaurus there is another ankylosaur from the Upper Cretaceous Europe, the remains of which were found in Austria and Romania. In the opinion of the first person describing it , Hungarosaurus might have been a little more developed than Struthiosaurus , but more primitive than the North American nodosaurids Silvisaurus , Sauropelta and Pawpawsaurus .
