Thylacine aka Tasmanian tiger

The thylacine was the largest known carnivorous marsupial of modern times. The thylacine had become extremely rare or extinct on the Australian mainland before European settlement of the continent, but it sur...vived on the island state of Tasmania along with several other endemic species, including the Tasmanian devil. Intensive hunting encouraged by bounties is generally blamed for its extinction, but other contributory factors may have been disease, the introduction of dogs, and human encroachment into its habitat. Despite its official classification as extinct, sightings are still reported, though none proven.
