The skull of an 8 million-year-old crocodile found in the Northern Territory in 2009 is now thought to be part of a new extinct species scientists never previously knew existed. Dr Adam Yates, senior curator of Earth Sciences at the Museum and Art Gallery of the Northern Territory, says the fossil is the best specimen ever found of a crocodile from the extinct Baru genus. He also says the find, 200 kilometres from Alice Springs, also shows Central Australia once had a river system capable of supporting life.
