Arkharavia
From the village of Arkhara (Amur Region, Far East Russia) and the Latin via (road); referring to the locality near the Arkhara River.
Arkharavia is a dubious genus of somphospondylan sauropod, although at least some of its remains probably belong to a hadrosaurid. It was discovered in the Udurchukan Formation in Russia and lived during the Late Cretaceous. It was described in 2010 by Alifanov and Bolotsky as the type species A. heterocoelica.
