The Tasmanian Tiger. Now extinct.
Photos found on the internet.
The thylacine, more commonly known as the Tasmanian tiger, was the largest marsupial carnivore to ever walk the Earth. It is believed that this creature went extinct in 1936.
A link to Wikipedia is here about the Tasmanian Tiger.
Once in awhile someone will say they have seen a Tasmania Tiger, but there is never any photo. Who know, there could be in our dense Tasmanian bush.
