Australia's largest flying reptile has been uncovered at Richmond, a pterosaur with an estimated seven-metre wingspan that soared like a dragon above the vast inland sea once covering much of outback Queensland.

University of Queensland PhD candidate Tim Richards, from the Dinosaur Lab in UQ's School of Biological Sciences, led a research team that analysed a fossil of the creature's jaw, which has been sitting on display at Richmond's Kronosaurus Korner for 10 years.

"It's the closest thing we have to a real-life dragon," Mr Richards said.

"The new pterosaur, which we named Thapunngaka shawi, would have been a fearsome beast, with a spear-like mouth and a wingspan around seven metres.

"It was essentially just a skull with a long neck, bolted on a pair of long wings."

Mr Richards said it would have been quite savage.

"It would have cast a great shadow over some quivering little dinosaurs who wouldn't have heard them coming until it was too late," he said.

Mr Richards said the skull alone would have been just over one metre long, containing around 40 teeth, perfectly suited to grasping the large predatory fishes known to inhabit Queensland's no-longer-existent Eromanga Sea.

"It's tempting to think it may have swooped like a magpie during mating season, making your local magpie swoop look pretty trivial - no amount of zip ties would have saved you," he said.

"Though, to be clear, it was nothing like a bird, or even a bat.

"Pterosaurs were a successful and diverse group of reptiles - the very first back-boned animals to take a stab at powered flight."

The new species belonged to a group of pterosaurs known as anhanguerians, which inhabited every continent during the latter part of the Age of Dinosaurs.

Being perfectly adapted to powered flight, pterosaurs had thin-walled and relatively hollow bones.

Given these adaptations their fossilised remains are rare and often poorly preserved.

"It's quite amazing fossils of these animals exist at all," Mr Richards said.

"By world standards, the Australian pterosaur record is poor, but the discovery of Thapunngaka contributes greatly to our understanding of Australian pterosaur diversity."

It is only the third species of anhanguerian pterosaur known from Australia, with all three species hailing from western Queensland.

Dr Steve Salisbury, co-author on the paper and Mr Richard's PhD supervisor, said this new species of anhanguerian had a massive sized bony crest on its lower jaw, presumably on the upper jaw as well.

"These crests probably played a role in the flight dynamics of these creatures, and hopefully future research will deliver more definitive answers," Dr Salisbury said.

The fossil was found in a quarry just northwest of Richmond in June 2011 by Len Shaw, a local fossicker who has been 'scratching around' in the area for decades.

The name of the new species honours the First Nations peoples of the Richmond area where the fossil was found, incorporating words from the now-extinct language of the Wanamara Nation.

"The genus name, Thapunngaka, incorporates thapun [ta-boon] and ngaka [nga-ga], the Wanamara words for 'spear' and 'mouth', respectively," Dr Salisbury said.

"The species name, shawi, honours the fossil's discoverer Len Shaw, so the name means 'Shaw's spear mouth'."

The fossil of Thapunngaka shawi is on display at Kronosaurus Korner in Richmond.

The research has been published in the Journal of Vertebrate Paleontology.
