Dinosaur skeletons unearthed in Russia

Three skeletons of gigantic dinosaurs, of which one may belong to a yet unknown species, were unearthed in Russia's Pacific far east.

Two of the skeletons belong to the hadrosaurus species, which could grow up to 12m tall. But the third remains a mystery.

The remains were found in a gigantic dinosaur gravesite near the village of Kundur in the Amur region.
