Thylacine
The thylacine ( THY-luh-seen; binomial name Thylacinus cynocephalus), also commonly known as the Tasmanian tiger, Tasmanian wolf or marsupial wolf is an extinct species of carnivorous marsupial which was native to the Australian mainland and the islands of Tasmania and New Guinea. The thylacine died out in New Guinea and mainland Australia around 3,600–3,200 years ago, possibly because of the introduction of the dingo, whose earliest record dates to around the same time, but which never reached Tasmania.
