INFO |
Two apparently intact skeletons had been found. Discovered on
the outskirts of the town of Blagoveshchensk. Despite the Late
Maastrichtian age proposed for the Blagoveschensk locality A.
riabinini looks verry primitive: its skull and dention present
several plesiomorphic characters not observed in North American
lambeosaurines. Its skull was probably capped with a crest similar
to that observed in the North American genera Corythosaurus
or Hypacrosaurus |
