when did the last tasmanian tiger go extinct
Thylacine The thylacine (/ˈθaɪləsiːn/ THY-lə-seen,[11] or /ˈθaɪləsaɪn/ THY-lə-syne,[12] also /ˈθaɪləsɪn/;[13] Thylacinus cynocephalus) was the largest known carnivorous marsupial of modern times. It is commonly known as the Tasmanian tiger (because of its striped lower back) or the Tasmanian wolf (because of its canid-like appearance, traits and attributes).[14] Native to continental Australia, Tasmania, and New Guinea, it is believed to have become extinct in the 20th century. It was the last extant member of its family, Thylacinidae; specimens of other members of the family have been found in the fossil record dating back to the late Oligocene.
Siberian tiger The Siberian tiger (Panthera tigris tigris),[3] also called Amur tiger, is a tiger population inhabiting mainly the Sikhote Alin mountain region in southwest Primorye Province in the Russian Far East. The Siberian tiger once ranged throughout Korea, Northeast China, Russian Far East, and eastern Mongolia. In 2005, there were 331–393 adult and subadult Siberian tigers in this region, with a breeding adult population of about 250 individuals. The population had been stable for more than a decade due to intensive conservation efforts, but partial surveys conducted after 2005 indicate that the Russian tiger population was declining.[1] An initial census held in 2015 indicated that the Siberian tiger population had increased to 480–540 individuals in the Russian Far East, including 100 cubs.[4][5] This was followed up by a more detailed census which revealed there was a total population of 562 wild Siberian tigers in Russia.[6]
