In the 21-second clip the animal, named Benjamin, is prowling around his cage at Beaumaris Zoo in Hobart, Tasmania, according to a press release.
The footage, released Tuesday, was filmed in 1935 for a travelogue called “Tasmania The Wonderland,” just a few months before Benjamin passed away.
Thylacines were large carnivorous marsupials that looked like a cross between a wolf, a fox, and a large cat. They hunted kangaroos and other marsupials as well as rodents and small birds, according to the Australian Museum.
They once lived throughout continental Australia but became extinct on the mainland around 2,000 years ago, perhaps due to competition with dingos and hunting pressure from humans, said the museum.
It was then confined to the island of Tasmania, where the remaining population declined due to the introduction of dogs and hunting by humans, who considered the thylacine a pest.
In the clip, which the NFSA digitized in 4K resolution, Benjamin can be seen pacing around while two men watch on rattling his cage.
The narrator says the thylacine “is now very rare, being forced out of its natural habitat by the march of civilization.”
Benjamin was the last known thylacine in captivity and these are the last confirmed moving images of the species. His death on September 7 1936 is thought to have marked the extinction of the species after another specimen died at London Zoo in 1931.
“The scarcity of thylacine footage makes every second of moving image really precious,” said NFSA Curator Simon Smith in a press release. “We’re very excited to make this newly-digitised footage available to everyone online.”
There are only around three minutes of black and white video of the species that have survived, filmed at both Beaumaris Zoo and London Zoo. No color footage has been found.
