Arkharavia heterocoelica gen. et sp. nov., a new sauropod dinosaur from the Upper Cretaceous of the Far East of Russia

Abstract

A new sauropod dinosaur, Arkharavia heterocoelica gen. et sp. nov., from the Maastrichtian (Udurchukan Formation) of the Amur Region, Russia, is described based on a tooth and several isolated anterior caudal vertebrae. It is distinguished by the saddle-shaped centrum and high neural spine of the anterior caudal vertebrae. Certain structural characters of the new genus are in common with Chubutisaurus insignis (Titanosauriformes) from the Upper Cretaceous of Argentina. © Pleiades Publishing, Ltd., 2010.
