The thylacine, more popularly known as the Tasmanian tiger, was an apex predator in Australia and Tasmania before its extinction in the early 20th century. Despite its superficial resemblance to a large dog, the thylacine was actually a marsupial, with no relation to canines The thylacine also featured an abdominal pouch similar to a kangaroo’s.
The last captive Tasmania Tiger, which was later referred to as ‘Benjamin’, spent several years behind bars in the Hobart zoo after being caught in the Florentine Valley in 1933. Its gender still a mystery, the animal died three years later on September 7, believed to be as a result of neglect. It was locked out of its sheltered sleeping quarters and died due to the exposure of an extremely cold Tasmanian night. The above is the animals final footage. (Source)
