Wulagasaurus is a genus of dinosaur that belonged to the group of hadrosaur dinosaurs. It lived approximately 69 million years ago, during the Cretaceous period, in what is now China. The first fossils of Wulagasaurus were discovered in the Wulaga Formation in Heilongjiang Province, providing paleontologists with valuable insights into this lesser-known dinosaur.

Our understanding of the physical characteristics of Wulagasaurus is limited due to the fragmentary nature of the fossil remains. However, based on related ornithopod dinosaurs, it is likely that Wulagasaurus was a medium-sized dinosaur, reaching lengths of approximately 9 meters and weighed approximately 3 tonnes.
