Dickson's Thylacine is closely related to the Tasmanian Thylacine, which became extinct during the 20th century. Its closest living relatives are now dasyurid marsupials such as quolls and the Tasmanian Devil.
Fossils of Dickson's Thylacine include an almost complete skull and skeleton as well as many individual teeth. They have been found at Riversleigh in north-western Queensland and at Bullock Creek in the Northern Territory.
