Buyer Opal Mike Poben made the discovery in 2013.

It can & # 39; deduce the two jaw fragments & # 39; 16mm and 25mm and information related species, he said.

Those key fragments could have lost, but for a lot of luck and a keen eye & # 39; P. Poben for opalizzati fossils.

He made the discovery at & # 39; August 2013, after having bought a couple & # 39; & # 39 bags; rough opal from Lightning Ridge Miner. One bag was not so good, so he put it up for sale. The other, he sifted through b & # 39; attention, know from past experience that "lower grade stuff" sometimes containing fossils.

"Pit or tooth is very rare. Extremely rare. More often than not is a bit of & # 39; wood … pine cones, Yabby buttons", he said. But sifting through the bag, something like teeth caught her eye.

"Something on the back of my head said" teeth ". I did not know it was a dinosaur but I would hope it was because teeth b & # 39; & # 39 form, fan are herbs," he said. "It was a crazy time. He was stunned."

Meanwhile, nobody bought the other bag. After nine & # 39; days, was returned to Mr Poben, and look at him very closely. "Sure enough there was a smaller piece, shiny on sides, tooth sockets … my first thought was" can not be another jaw bones'. "

He picked up the other piece, qabbelhom, and realized that it was made even more incredible discovery.

"If there was a film was golden sunbeam … two pieces from the same jaw."

Mr Poben took the jaw fragments to the Australian Opal Center in & # 39; Sightning Ridge, who informed Dr Bell and team UNE f & # 39; Armidale.

After two years & # 39; study, the team was able to identify the new species, with their research published in the journal Peerj Tuesday.

Dr. Bell said while the fossils found in the opal fields of Australia, Lightning Ridge is the only one that produces dinosaurs. And because some discoveries are contingent on sifting through & # 39; & # 39 tiny fragments; "Catch" the opal mining, species that scientists were able to identify up to now the very tip of the iceberg.

"It is truly remarkable ecosystem still tell us new things", said Dr Bell. "Even now new species will eventually recover mentioned a little more & # 39; away."

Scientific Treasury by-product of mining

"If these fossils were the rock face, like those found in China and Mongolia, is an absolute treasure", said Dr Bell. But the rock of Australia face before the dinosaurs, so it is only through & # 39; opalised fossil that scientists can get a picture & # 39; local species.

This presents a "unique" scenario, since the opal mining process reduces fossil to the caller – but nevertheless plays an essential role.

"All these rocks are underground", said Dr Bell. "The right kind of & # 39; rocks are not anywhere exposed on the surface. On a normal posting & # 39; dinosaur we & # 39; d be walking around looking face bits & # 39; bones. M & # 39; We should such luxury in Lightning Ridge.

"While it can & # 39; my heart is to see if bone was once completed, not seeing anything."

That is why the university now looking at some mines that are not economically viable but are known to produce fossil.

"As always paleontologi are dealing with missing information," said Dr. Bell. "We & # 39; re miners debt altogether."
