Zhongyuansaurus (meaning “Zhongyuan lizard”) is a monospecific genus of ankylosaurid dinosaur from Henan that lived during the Early Cretaceous (Aptian-Albian, ~125.0-100.5 Ma) in what is now the Haoling Formation.

[2] The synonymization of Zhongyuansaurus is based on the holotype having all the diagnosable characteristics of Gobisaurus, except for features that cannot be assessed because of damage, like having vomers with elongated premaxillary processes.

[3] Although the holotype specimen represents an immature individual based on cranial sutures, ontogeny does not seem to be an explanation for the absence of the knob osteoderms.

[3] Xu et al., 2007 originally considered Zhongyuansaurus to be a nodosaurid ankylosaur based on the skull proportions and the absence of a tail club.
