The Thylacine, more commonly known as the Tasmanian Tiger, was a carnivorous marsupial about the size of a Doberman, with all the scariness of one. It had crushing jaw power (it could open its mouth to almost a 90 degree angle), was a quick, solitary hunter, and good with camouflage. For years, it was at the top of the Aussie and Tasmanian food chains. However, this was a creature that freaked out even the Australians, so they put a bounty on their heads, and the last one died in the Hobart Zoo in the 1930′s. But it took more than hunting to do it in. Other factors included introduction of the dingo into the Australian mainland, driving it off onto only Tasmania (competition for similar foods went up) and deforestation. But if you want this guy to come back, it may happen someday, as some scientists think there’s a possibility of restructuring DNA fragments from a preserved baby thylacine, and there are tons of conspiracy theorists that think it’s still hiding out there in Tasmania.
