The Thylacine was the largest known carnivorous marsupial of modern times. Native to Australia and New Guinea, it is thought to have become extinct in the 20th century.
It is commonly known as the Tasmanian Tiger (because of its striped back), the Tasmanian Wolf, and colloquially the Tassie (or Tazzy) Tiger or simply the Tiger. It was the last extant member of its genus, Thylacinus, although several related species have been found in the fossil record dating back to the early Miocene.
The Thylacine became extinct on the Australian mainland thousands of years before European settlement of the continent, but it survived on the island of Tasmania along with several endemic species, including the Tasmanian Devil.
Intensive hunting encouraged by bounties is generally blamed for its extinction, but other contributory factors may have been disease, the introduction of dogs, and human encroachment into its habitat. Despite being officially classified as extinct, sightings are still reported.
