A group of Tasmanian Tiger enthusiasts claim they've captured a living Thylacine on video footage - 80 years after the species was believed to have gone extinct.

"I don't think it's a thylacine, I know it's a thylacine," said Adrian 'Richo' Richardson of the grainy video footage which shows a creature at a distance. 

Richardson, along with Joe Booth and Greg Booth calls themselves the Boot Richardson Tiger Team (BRTT).  They set up 14 wildlife capture cameras at various spots around Maydena, Tasmania, changing the locations every two weeks.  The team recorded the footage last November and released it today - one day before the 81st anniversary of the death of the last known Thylacine, nicknamed Benjamin, at the Hobart Beaumaris Zoo in 1936.  There have been numerous sightings ever since, although none were convincing or accompanied by evidence.

Local wildlife expert Nick Mooney examined the footage:  "I think based on anatomy, movement, behavior, size, I think it is perhaps a one-in-five chance it's a thylacine," he said, suggesting that the video might actually show a very large spotted-tailed quoll.
