From Scott Casey at The Age:
Unveiled today at the Queensland Museum, the largest dinosaur bones found in Australia came from the remains of two titanosaurs uncovered in the Winton Formation (100 million years ago), west of Charleville, in 2005 and 2006.
"We don't have a scientific name for this type of titanosaur because we believe they are a new type of species," Queensland Museum curator of geosciences, Scott Hocknull, said.
"These are the largest bones ever discovered in Australia. They would have been about two buses in length." The largest of the bones measures 1.5 metres long and weighs 100kg.
