"Despite their "tiger" sobriquet, thylacines are not members of the cat family. Nor should they be confused with the Tasmanian devil (Sarcophilus harrisii), another carnivorous marsupial that is native to Australia and is still widespread in Tasmania.
Fossil evidence suggests that the modern thylacine — Thylacinus cynocephalus, whose name means "dog-headed pouched one" — emerged about 4 million years ago. Once widespread across Australia, the animal disappeared everywhere except Tasmania about 2,000 years ago, according to the National Museum of Australia (NMA)." livescience.com
Seems to me there was a movie a while back in which Willem Dafoe as a hunter stalks the last Tasmanian Tiger. As a recovering hunter I could really identify with this character and understand his emotions when he finds one that is sick, old and alone and finishes her off.
I sure hope there are some left up there in Queensland hanging out with the box jellies, salt water crocs and all the rest. pl
