Dvinosaurus

Description

Dvinosaurus is an extinct genus of amphibious temnospondyls localized to regions of western and central Russia during the Late Permian, approximately 265-254 million years ago. Its discovery was first noted in 1921 by Russian paleontologist Vladimir Prokhorovich Amalitskii in a posthumously published paper that documents the findings of a site in Russia's Arkhangelsk District. Its name is derived from the proximity of this site to the Northern Dvina River.
