The thylacine, known as the Tasmanian tiger, was the largest carnivorous marsupial of modern times before it disappeared for good on 7 September 1936, when the last known individual died in Hobart's Beaumaris Zoo. This footage, shot in 1933 by naturalist David Fleay, shows one of the animals still alive, pacing its enclosure and yawning wide enough to reveal the jaw's unusual range of motion, opening to about 120 degrees, far beyond what most mammals manage. The mouth also carries 46 teeth, more than most carnivorous marsupials, an adaptation built for a predator that hunted rather than scavenged. There is no narration or context beyond the animal itself on camera, just a rare direct look at a species that vanished from the planet within a few years of the recording.
