Like with Liaoningosaurus, Zhongyuansaurus was first described as a nodosaurid, but later identified as an ankylosaurid. Further study has identified Zhongyuansaurus as the most basal (primitive) ankylosaurine, the group of ankylosaurs that contains the more advance forms that began to appear as the Cretaceous progressed. So basal in fact was Zhongyuansaurus, that it didn’t even have the club on the end of its tail that is such a familiar feature for most other ankylosaurine genera.
