A complete, frozen carcass of a Steppe bison that lived approximately 9,300 years ago has been discovered in Russia’s Far East, Russian and American scientists announced on Thursday. It is the most complete find yet of the animal which became extinct thousands of years ago.
The frozen carcass, which has been named the Yukagir bison mummy, was recently uncovered in the Yana-Indigirka Lowland of Eastern Siberia. The carcass has a complete brain, heart, blood vessels and a digestive system, making it the most complete find to date for this species, although some of its organs have shrunk over time.
“The exclusively good preservation of the Yukagir bison mummy allows direct anatomical comparisons with modern species of Bison and cattle, as well as with extinct species of bison that were gone at the Pleistocene-Holocene boundary,” said Dr. Evgeny Maschenko of the Paleontological Institute in Moscow.
