The Tasmanian Tiger

Thylacines - Greek for dog-headed pouched one - were the largest known carnivorous marsupial of modern times, top-level predators native to continental Australia, Tasmania and New Guinea.

Commonly known as the Tasmanian Tiger due to its striped back, they were the last extant member of their genus, Thylacinus.

These creatures became extinct on the Australian mainland thousands of years before European settlement of the continent, but survived on the island of Tasmania. It's thought that intensive hunting encouraged by bounties to be blamed for their extinction, but other contributing factors may have been disease, the introduction of dogs, and human encroachment into their habitat.
