: In prehistoric times the Tasmanian tiger ranged from Tasmania, mainland Australia to New Guinea. However, in recent times the Tasmanian tiger was restricted to the Australian island of Tasmania. The Tasmanian tiger preferred open forests and open grasslands, but by the end of its existence it was confined to dense rainforests by human pressures Tasmanian tiger lairs were located mainly in hollow logs or rock outcroppings located in hilly areas that were adjacent to open areas, such as grasslands. The food habits of the Tasmanian tiger are not well known. Its diet is thought to have consisted of wallabies, kangaroos, small birds, and other small mammals.
