Scientists have discovered Australia's toughest dinosaur had an extra raptorial type claw which it would use to penetrate deep into its prey ensuring it didn't escape and could be eaten fresh.

The revelation comes as more clues were discovered in western Queensland to piece together the structure of one of Australia's deadliest dinosaurs: Banjo aka Astralovenator.

Until recent years little was known about Banjo or the general dinosaur population which would roam the Australian landscape millions of years ago.

In 2006 remains of Banjo were discovered leading to the conclusion more called Australia home than first thought.

Palaeontologist Matt White said many key bones of Banjo have revealed details previously not known.

"We've found around another 20 or 30 pieces from his actual skeleton but what was most interesting is we found a really large second claw to his hand.

"That's told us quite a bit about his predatory behaviour because the other bones we also found helped us articulate a full arm.

"So what we could then do is work out how the whole arm moves and how he grasped his prey," he said.

The recent discoveries were solidified when Matt inquired into using scanning machine while he was receiving medical treatment in Mackay.

"I was underneath the CT scanner and I just happened to ask the guy 'do you reckon we can CT scan some dinosaur bones here?'

"They finally worked out that I was serious and said 'look we'd love to scan your bones' and what we ended up being able to do is see the internal structures of the dinosaur bone and we could import them into various computer packages," he said.

Matt said this process painted a clearer picture on the size and shape of Banjo's claw.

'Initially we weren't quite sure of the size of the second claw... now we believe it was like a raptorial claw.

"So as soon as he came across any prey item and those claws got a hold of them, it didn't matter how much that prey struggled those claws just went further and further into the prey.

"Even if those first claws slipped he had this huge second claw to further grasp the prey as well so instead of just having one claw in his hand he had two massive meat hooks," he said.

Matt said there were still many more digs to occur which would give greater indication of the size and shape of Banjo.

David Elliot founded the Australian Age of Dinosaurs Museum in Winton and was behind some of the initial discoveries of Banjo when he was mustering a paddock.

David is confident more dinosaur bones in Australia will be discovered leading to the better understand of the Australian landscape millions of years ago.

"The old saying was that there was nothing in Australia, they always assumed it was a continent that very very little in the way dinosaur life on it and that's because historically there's been so little found... you could've put the whole lot in a ute.

"We know of over 30 sites in the district waiting to be dug and when you look at that... there's massive resources here and we're probably going to spend the next five decades working on at least," he said.

David said the latest discoveries will mean the museum will thrive.

"We're pushing the education, we're pushing the science to try and get the whole thing to grow.

"We can dig a lot more, we can prepare a lot more and get more scientists involved to describe it and the whole thing is just starting to take off," he said.
