Mega-marsupials once roamed Australia...
Marsupial lions were kangaroos as big as Godzilla. They lived in remote regions of Australia 400,000 years ago. As soon as the first Aussie came to Australia and opened a marsupial resturant, they became a goner (or was it global warming?)
The question is: have you seen the kangaroo-beast in Star War V (the Empire Strikes Back)? Is that one of the marsupial lions? If so, is Star War a film about ancient Australian zoology?
