Paleontologists working at an undisclosed fossil bed in the Northern Territory's outback have discovered at least two new marsupial species including a wombat-like creature that could have weighed about 50 kilograms.
The discoveries were made at the roughly 25-million-year-old Pwerte Marnte Marnte site near Rainbow Valley, south of Alice Springs, which is thought to be one of Australia's oldest land mammal-bearing fossil beds.
