Giant prehistoric marsupial found in Northern Australia

The excavation team, comprised of students and researchers from several Australian colleges and universities and led by project leader Professor Michael Archer of the University of New South Wales, has shipped the find to Mount Isa for further study. The skeleton was found in north-west Queensland's Gulf of Carpentaria region, and was first noted last year when a group unearthed a large leg bone, unaware of the rest of the skeleton buried nearby. It was only when they returned this year to investigate further did they find the rest of the skeleton. After further study and preparation at the Riversleigh Fossil Center, the skeleton will be put on display at the Queensland Museum.

Researchers are excited about the find because they believe it will help to fill in missing information about not just the diprotodon, but about early Aboriginal culture as the two are believed to have co-existed; and indeed one rib found at another site had a small square hole through it that many believe came about as the result of a spear strike.

The diprotodon, described as an SUV sized wombat, is believed to be the largest marsupial ever to have walked the earth, weighing in at some three tonnes (3000 kilograms) and stretching to 14 feet long (4.3 meters). A herbivore, the giant beast would have presented a challenge to early predatory humans nonetheless if was anything like a wombat, which has sharp rodent-like teeth and has been known to bite, charge and bowl over those that cause it alarm.

Because all of the bones were found together, the research team believes many more specimens, including those of other mega fauna, might be found in the area as well.
