Книга: Caspian Tiger: Siberian tiger, Kazakhstan, Tajikistan, Extinction, Subspecies, Berlin Zoological Garden

The Caspian tiger (formerly Panthera tigris virgata), also known as the Persian tiger, Turanian tiger, Mazandaran tiger or Hyrcanian tiger was the westernmost population of Siberian tiger, found in Iran, Iraq, Afghanistan, Turkey, Mongolia, Kazakhstan, Caucasus, Tajikistan, Turkmenistan, and Uzbekistan until it apparently became extinct in the late 1950s, though there have been several alleged sightings of the tiger. Though originally thought to have been a distinct subspecies, known as Panthera tigris virgata genetic research in 2009 proved that the animal was virtually identical to the Siberian tiger (P. t. altaica).
