The Tasmanian tiger, the largest known carnivorous marsupial, was wiped out of the wild due to constant hunting:
Darya [45]

The statement is - True.

The Tasmanian tiger went extinct because of the extensive hunting by the new settlers. People were killing the Tasmanian tiger because they thought that it is the animal responsible for the killing of the livestock, but at the end it turned out that they made a huge mistake and that actually the feral dogs and the dingo were the ones responsible for that. The last Tasmanian tiger was a female and died in captivity under very bad conditions.

Even though people use the term Tasmanian tiger (because of the stripes) and Tasmanian wolf (because of the dog-like face), it is an animal that is not related with neither the cats nor the dogs, but instead it is a marsupial, the biggest marsupial carnivore in the recent history, and its real name is Thylacine.
