Charonosaurus jiayinensis n.g., n.sp., a lambeosaurine dinosaur from the Late Maastrichtian of northeastern China

Large bonebeds have been excavated in the Fate Maastrichian Yuliangze Forma tion near Jiayin (Heilongjang Province, northeastern China). The greatest p art of the discovered fossils belong to a new lambeosaurine dinosaur, Charo nosaurus jiayinensis n.g., n.sp. Phylogenetic analysis, based on 33 cranial , dental and postcranial characters, indicates that this new taxon may be c loser to Pardsaurolophus than any other known Lambeosaurinae. The Late Maas trichtian dinosaur faunas currently known in northeastern Asia are dominate d by Lambeosaurinae, although these dinosaurs are not represented any more in synchronous North American and European localities.
