Thylacine was a carnivorous (mainly meat eating) marsupial animal. The Thylacine was also known as a "Tasmanian tiger", a "Tasmanian wolf" and a "Tasmanian hyena". The last known Thylacine died in a Hobart zoo on 7 September 1936. They once lived across Australia and New Guinea. There are paintings of the animals in the north of Western Australia, and in the Northern Territory. At Riversleigh in north Queensland, scientists have discovered the fossil bones of thylacines that are at least 30 million years old.
