The extinct Thylacine Thylacinus cynocephalus, also known as the marsupial wolf or Tasmanian Tiger, is an iconic part of Australia’s natural history. The latest surviving member of the diverse family Thylacinidae, the thylacine was widespread across mainland Australia during the Pleistocene but by 3200 ybp it was restricted to Tasmania. Persecuted by farmers, thylacines are thought to have gone extinct in the wild by the 1930s, and the last surviving captive animal died in 1936. Despite much public interest and numerous popular accounts, the ecology of this iconic Australian species is not well known. Though huge numbers of animals were killed during the extermination of thylacines from Tasmania, very few useful specimens exist in collections. For palaeontologists, access to comparative material is important but not always practicable. The purpose of this atlas is to provide a comprehensive record of the skeletal anatomy of the Thylacine to provide researchers a useful reference for comparative studies.
