A video possibly showing a long-thought extinct Tasmanian tiger has been posted online by a group that believes the thylacine can still be found on mainland Australia.
The animal was filmed in the Adelaide Hills in February this year with the video posted on Monday on the Facebook page of the Thylacine Awareness Group.
It shows an animal with a long, thick tail and what could be stripes on the body and amateur researcher Neil Water says the group believes it is a small thylacine.
"We believe our footage to be footage of a small thylacine moving around through the Adelaide Hills only 20 minutes from the CBD of Adelaide," Mr Waters said.
"You can see the body of the animal, it does appear to have some sort dark discolouration which may or may not be stripes.
"It has a long, stiff, pointy tail. Where the tail connects to the body is very wide at the base which is typical of the thylacine."
The last known Tasmanian Tiger died in the Hobart Zoo in 1936.
But there have been numerous unconfirmed sightings over the years, some in Tasmania and some on mainland Australia.
Intensive hunting along with the introduction of dogs and the loss of habitat have been blamed for the extinction of the species.
