Genus Wulagasaurus nov.

Type species: Wulagasaurus dongi sp. nov., from the Yuliangze Formation ( Maastrichtian , Upper Cretaceous) of Wulaga, Heilongjiang province, China .

Derivation of the name: Wulaga is the type locality of this new genus; sauros, the Greek for lizard.

Diagnosis.—Hadrosaurine dinosaur characterised by the following autapomorphies: very slender dentary, with a ratio “length of the dentary battery/maximum height of the dental ramus taken around the middle of the dental battery”>4.5; lateral side of dentary not pierced by foramina; edge of the deltopectoral crest oriented quite cranially; humeral articular head extends distally as a very long and prominent vertical ridge; inner tuberosity much better developed than outer tuberosity on the proximal end of the humerus.

Also differs from all other known hadrosaurines by its short sagittal, less than 2/3 the length of the parietal; differs from Gryposaurus , Kerberosaurus , Prosaurolophus , Saurolophus , Edmontosaurus , and Anatotitan by its short supraoccipital−exoccipital shelf.
