Zhongyuansaurus is a little-known genus of pelvic dinosaurs from the Ankylosauria group , the remains of which were described in 2007.
From zhongyuansaurus only parts of are far skull , the front legs, the pelvis and tail known. The skull of these dinosaurs was elongated (1.4 times as long as it was wide) and also characterized by a flat parietal bone and a flat area behind the eye socket - in many other ankylosaurs, clear outgrowths can be seen here. There are other special features in the structure of the humerus . Otherwise little is known about the physique of Zhongyuansaurus , probably like all ankylosauria it was a quadruped (four-footed) dinosaur with a stocky build, which was covered with an armor made of bone plates and ate plants.
The fossil remains of Zhongyuansaurus were discovered in the Chinese province of Henan and first described in 2007 . The type and only known species is Z. luoyangensis . The finds are dated to an age of about 100 to 89 million years in the early Upper Cretaceous .
Zhongyuansaurus was systematically classified by its first descriptors because of the structure of the skull and the tail within the Ankylosauria in the Nodosauridae .
