==Distribution and habitat== The thylacine most likely preferred the [[Flora of Australia|dry eucalyptus forests, wetlands, and grasslands]] of [[Australia (continent)|mainland Australia]].<ref name="tasparks" /> Indigenous Australian rock paintings indicate that the thylacine lived throughout mainland Australia and [[New Guinea]]. Proof of the animal's existence in mainland Australia came from a [[desiccated]] carcass that was discovered in a cave in the [[Nullarbor Plain]] in Western Australia in 1990; [[carbon dating]] revealed it to be around 3,300 years old.<ref name="nma">{{cite web|url=https://www.nma.gov.au/about/media/media-releases-listing-by-year/2004/mummified-thylacine-has-national-message |title=Mummified thylacine has national message |publisher=National Museum of Australia, Canberra|date=16 June 2004|access-date=15 September 2020|archive-url=https://web.archive.org/web/20131110112250/http://www.nma.gov.au/media/media_releases_by_year/2004/2004_06_16|archive-date=10 November 2013|url-status=live}}</ref> Recently examined fossilised footprints also suggest historical distribution of the species on [[Kangaroo Island]].<ref>Fedorowytsch, T. 2017.
