The Wannanosaurus' common name is the Wannan lizard. Hou Lian-Hai discovered remains of this species in a small region of China now known by the name Anhui. These fossils state that the species of this genus belonged to the Cretaceous era, which existed almost 80 million years ago. Even though the detailed physical description of these dinosaurs of the Wannanosaurus genus is unknown, they are distinctively famous in the dinosaur fanbase for their skulls. Why? Based on fossils found, it was clear that these animals had flat skulls, which made them fascinating. The analysis of these fossil studies suggests that they had strong lower legs and used their strength and flat heads during confrontation and combats.

This dinosaur belonged to the Pachycephalosauridae family of animals. There were a few debates about it being a herbivore or a carnivore. Significant research finally added this species to the herbivore category, which is still debatable; hence, they are also considered omnivores.
