RESEARCH CATCHING the MARSUPIAL ‘LION’ by the TAIL: THYLACOLEO CARNIFEX and the NARACOORTE CAVES Michael Curry, Liz Reed1,2 and Steve Bourne3 1School of Physical Sciences, The University of Adelaide, Adelaide, SA, Australia; 2School of Biological Sciences, Flinders University, Bedford Park, SA, Australia; 3Naracoorte Lucindale Council, Naracoorte, SA, Australia. “Thylacoleo exemplifies the simplest and most effective dental machinery for predatory life and carnivorous diet known in the Mammalian class. It is the extreme modification, to this end, of the Diprotodont type of Marsupialia.” Owen (1866) Introduction defending Thylacoleo as “A very gentle beast, and of good conscience” (Macleay 1859). Macleay based his Of all the extinct Australian Pleistocene megafauna argument on Thylacoleo’s relationship with other species, Thylacoleo carnifex (the marsupial ‘lion’) has Diprotodont marsupials, most of which are herbivores. captured the imagination and interest of people more Gerard Krefft, Curator of the Australian Museum, was than any other. Perhaps it is the allure of its predatory almost equally as unimpressed with Thylacoleo’s habits, (Australia’s Pleistocene answer to T. rex); or the carnivory, opining that it “…was not much more intriguing notion that it used caves as dens (Lundelius, carnivorous than the Phalangers (possums) of present 1966 ). It is certainly an enigma and, as Owen (1866) time.” (Krefft, 1866). Owen, meanwhile, had received an suggested, an extreme and meat-eating version of the almost complete skull from the Darling Downs, in otherwise herbivorous diprotodont marsupials. Queensland and published a more detailed paper, Spectacular fossil finds over the past few decades have further describing the skull and teeth of Thylacoleo, put to rest much of the speculation regarding its habits acknowledging its diprotodont affiliation but more and morphology.
