Thylacoleo ("pouch lion") is an extinct genus of carnivorous marsupials that lived in Australia from the late Pliocene to the Late Pleistocene (until around 40,000 years ago), often known as marsupial lions. They were the largest and last members of the family Thylacoleonidae, occupying the position of apex predator within Australian ecosystems.
The best known is Thylacoleo carnifex, also called the marsupial lion. [3] The clade ranged from the Late Oligocene to the Late Pleistocene, with some earlier species the size of a possum, while the youngest members of the family belonging to the genus Thylacoleo reached sizes comparable to living big cats.
Genus Thylacoleo; The specific epithet attenboroughi commemorates the enthusiasm and support provided by David Attenborough, a well known broadcaster of natural history, that increased the recognition of the species type location, the Riversleigh World Heritage Area, a fossil site he described as one of the four most important.

The theory of continued Thylacoleo presence on mainland Australia and thylacine presence in Tasmania has been covered on various Television shows including an episode of Animal Planet's show Animal X and on The National Geographic Channel. Individual sightings of the Queensland marsupial tiger continue to appear in newspapers, though in far ...
Opponents of this hypothesis meanwhile highlight how Quinkana was relatively rare, whereas large marsupial predators like Thylacoleo were much more common. Regardless of its lifestyle and behavior, Quinkana is predominantly found in sediments preserving various types of woodland in proximity to bodies of water such as ponds, streams and billabongs.
Thylacosmilus is an extinct genus of saber-toothed metatherian mammals that inhabited South America from the Late Miocene to Pliocene epochs.Though Thylacosmilus looks similar to the "saber-toothed cats", it was not a felid, like the well-known North American Smilodon, but a sparassodont, a group closely related to marsupials, and only superficially resembled other saber-toothed mammals due to ...
