Scientists have discovered a new species of dinosaur in Australia, which they believe is one of the largest to ever roam the earth. The Australotitan cooperensis, nicknamed the "southern titan," is estimated to have been up to 30 meters long and weighed up to 70 tons. The bones of the dinosaur were first discovered in 2007 in southwest Queensland, but it took years of research and comparison to confirm that they belonged to a new species. The discovery may provide new insights into how dinosaurs evolved in Australia.
