Dongyangosaurus is a genus of titanosaurid dinosaur that is known to have lived in China at some point during the earlier stages of the late Cretaceous, Though only known from partial remains, Dongyangosaurus has been confidently identified as a saltasaurid titanosaur, and similar in form to Saltasaurus which is known from South America. The genus that Dongyangosaurus seems to be closest too however is Opisthocoelicaudia from Mongolia. Overall it is unknown if Dongyangosaurus had any bizarre features, or even if it had similar bony armour plates in the skin that Saltasaurus is known to have had. The pubic bone of Dongyangosaurus is notably shorter than the ischium however, something that in dinosaurs as a whole is usually the other way around.
