[D] Charonosaurus jiayinensis [Su] [sG] [T]
Describer
Godefroit, Zan & Jin, 2000
Time
Cretaceous Late Maastrichtian
Classification
Ornithischia Ornithopoda Hadrosauridae Lambeosaurinae
Diet
Herbivore
Fossilsite
Yuliangze Formation, \\\\\\\" Belyie Kruchi\\\\\\\", on the southrn banks of the Amur (Heilongjiang) River, west of the village of Jiayin, Heilongjiang Province, northeastern, China
Length
13 meter
Info
Genus - Typespecies - Skull
The holotype specimen is a partial skull. Most [but not al] of the crest is broken off, but what remains resembles the crest of Parasaurolophus. Besides the holotype skull there is plentiful disarticulated postcranial material from a bone bed, and a Parasaurolophus-like skeletal reconstruction appears in the paper.
The holotype specimen is a partial skull, (CUST J-V1251-57) presently in the collection of the Changchun University of Sciences and Technology. Lamentably, almost all of the crest is missing, but enough skull bones exist to indicate that the shape of the crest was similar to that of the North American genus Parasaurolophus.
Besides the holotype skull there is plentiful disarticulated postcranial material from a bone bed, CUST J-III and J-V, skull and postcranial elements; GMH Hlj-16-77-87-101-140-143-144-178-195--196-207- 278-A10-A12 and the [\\\\\\\"Mandschurosaurus magnus\\\\\\\"] skeleton.
It\\\\\\\'s a big hadrosaur, around 13 meters long, in Asia second in size only to Shantungosaurus. Several large bonebeds of this dinosaur have been and are being excavated, all nearly monospecific and evidently river accumulations (the bones are disarticulated, jumbled together, and show a preferential direction), and from these a nearly complete skeletal reconstruction is depicted.
The name comes from Charon, the \\\\\\\"boatswain of the Styx River in Greek and Roman mythology.\\\\\\\" The paper does not specifically mention why this personage was chosen for the name, but it may have to do with the riverine nature of the deposits or with the fact that the type locality is on the right bank of the Amur River (Heilongjiang). Type horizon is the Yuliangze Formation. All the material is being prepared for further study and publication.
The paper distinguishes Charonosaurus jiayinensis from another lambeosaurine species discovered in nearly monospecific bonebeds from the same region, Amurosaurus riabinini. Mandschurosaurus is possible a junior synonym of Charonosaurus, in which case the former has priority.
