Despite their name and appearance, these dog-like creatures were not tigers or canids. Rather, they were marsupials. In fact, they were the largest carnivorous marsupials of modern times.
Native to mainland Australia and Tasmania, they were declared extinct as recently as the 1930s after a century of intensive hunting encouraged by bounties (farmers feared that the tigers were killing their sheep).
The last known wild Tasmanian tiger was killed by a farmer named Wilf Batty, who shot the animal after it had been sighted patrolling outside of his house.
