The Thylacine (Thylacinus cynocephalus) was the largest known carnivorous marsupial of modern times. Native to Australia and New Guinea, it is thought to have become extinct in the 20th century. It is commonly known as the Tasmanian Tiger (due to its striped back), the Tasmanian Wolf, and colloquially the Tassie (or Tazzy) Tiger or simply the Tiger.[a] It was the last extant member of its genus, Thylacinus, although a number of related species have been found in the fossil record dating back to the early Miocene.
The Thylacine became extinct on the Australian mainland thousands of years before European settlement of the continent, but survived on the island of Tasmania along with a number of 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 being officially classified as extinct, sightings are still reported.
Sightings are still reported, and apparently filmed on occasion as well. Loren Coleman has collected a number of these videos from YouTube and posted them here. I've picked the best of them, and coupled it with some zoo footage from the early 20th century so you can get an idea of how the animals typically moved. Note that the first few seconds of the zoo footage may be film of the creature in the wild, but its pretty grainy. Both clips are from Cryptomundo.
Tiger In The Wild?
Note that the hindquarters do seem appropriately striped.
