Wulagasaurus is one of many hadrosaurs that have been found from the Amur River region. Although the genus is represented by a collection of scattered fossils in a bone bed, Wulagasaurus seems to have been a saurolophine hadrosaurid that was possibly related to Maiasaura and Bachylophosaurus. Wulagasaurus was not the only new hadrosaur discovered near the Amur River in 2008, the same team also described the lambeosaurine Sahaliyania at the same time as Wulagasaurus.
