Thylacine (Tasmanian Tiger)

The thylacine, a marsupial native to Tasmania, was hunted to extinction in the early 20th century. Known for its wolf-like appearance and distinctive stripes, the thylacine was feared by farmers who blamed it for livestock deaths. The last known thylacine died in captivity in 1936.
Cause of Extinction: Overhunting and habitat destruction.
There have been numerous reported sightings since its official extinction, but none have been confirmed.
