What was the other name for the extinct tiger subspecies, which inhabited the sparse forests and riverine corridors west and south of the Caspian Sea, from Turkey, Mesopotamia, Iran and the Caucasus, that has a project reestablishing populations of the Siberian tiger by introducing them as replacements to the extinct tiger?
Siberian Tiger Introduction Project The Siberian Tiger Introduction Project involves reestablishing populations of the Siberian tiger ("Panthera tigris altaica)", also known as the Amur tiger, in their former range and also expanding their range by introducing them as replacements of their genetically similar relative, the extinct Caspian tiger ("Panthera tigris virgata") which inhabited Central and Western Asia. Currently, the Siberian tiger inhabits the cold mountains of the Russian Far East and northern China.
Scythian languages The Scythian languages ( or ) are a group of Eastern Iranian languages of the classical and late antiquity (Middle Iranian) period, spoken in a vast region of Eurasia named Scythia. Except for modern Ossetian, which descends from the Alanian variety, these languages are all considered to be extinct. Modern Eastern Iranian languages such as Wakhi, however, are related to the eastern Scytho-Khotanese dialects attested from the kingdoms of Khotan and Tumshuq in the ancient Tarim Basin, in present-day southern Xinjiang, China.
