BRISBANE, Australia?Scientists on Wednesday revealed they have uncovered fossilized fragments of a large dinosaur which may be unique to Australia.

The giant animal has been named ?Elliot? after a family member of the rancher who first discovered its fossil in central Queensland state in 1999. The find was kept secret until Wednesday so paleontologists could excavate the site without disturbance.

Queensland Museum paleontologist Steve Salisbury said Elliot is the largest dinosaur ever found in Australia and belongs to the sauropod group.

Researchers believe it would have been between 48 and 63 feet long and would have weighed more than 30 tons.

?It could turn out to be the most complete sauropod that?s ever been found in Australia, in addition to being the largest,? Salisbury said.
