Charonosaurus
''Charonosaurus'' ( ; meaning "Charon's lizard") is the name of a genus of dinosaur whose fossils were discovered by Godefroit, Zan & Jin in 2000 on the south bank of the Amur River, dividing China from Russia.
==Description==
''Charonosaurus'' is a very large lambeosaurine hadrosaur (estimated around 10 m (33 ft) long),〔Holtz, Thomas R. Jr. (2012) ''Dinosaurs: The Most Complete, Up-to-Date Encyclopedia for Dinosaur Lovers of All Ages,'' (Winter 2011 Appendix. )〕 known from a partial skull (Holotype: CUST J-V1251-57 (Changchun University of Sciences and Technology, Changchun, Jilin Province, China) found in the Late Maastrichtian Yuliangze Formation, west of Jiayin village, Heilongjiang Province, northeastern China. Adult and juvenile hadrosaur remains discovered in the same area and formation likely represent the same taxon and supply information on most of the postcranial skeleton; the femur length was up to 1.35 m. (4.5 ft). The partial skull resembles that of ''Parasaurolophus'' and probably had a similar long, backward-projecting hollow crest, indicated by the highly modified dorsal surface of the frontal bones. ''Charonosaurus'' is one of the largest hadrosaurs currently known from Asia and indicates that lambeosaurines survived until the very end of the Cretaceous (lambeosaurines are not known from the Late Maastrichtian in North America).〔
