A new genre of dinosaur was discovered after a "fascinating" fragment of fossilized fossilized jawbone found among a bucket bucket rejected from an opal mine in Australia.
The fossils come from reptiles with a tree, lived in the Cretaceous Century, about 100 million years ago and is part of a group of soil dinosaurs, known as ornithopods.
Found near Lightning Ridge, New South Wales, this group was packed with depressing teeth, they walked on two legs and were particularly abundant on the old floodfalls that were in the past. ; the area's cover at that time.
He was named as Weewarrasaurus pobeni in recognition of the position of the source, at the Wee Warra opal range and describing Mike Poben, an Adelaide-based Opal merchant who saw the quadrilateral and presented for research.
"I arranged a little opal rough when I was surprisingly, I saw two sides similar to the path that flows from the sea around one piece of unusual shapes," he said. "The time was running. If they had a dentist, it's a jawbone clip here."
Lightning Ridge is believed to be the only place in the world where every fossil is there, They are preserved in a precious multi-brown opal – stone.
The Australian opal archive accounts for more than 95 per cent of world supply, and Lightning Ridge is the main source of blackberry. As a result, there are many mines in the area.
The fossil traces "are the result of the almost exclusively mineral process, which is unfortunately affecting the breakdown and / or inadequate absorption and loss of detailed stratographic information," which Describing a research paper about the discovery, published in the magazine Seisear J.
Pictures that show extended silent teeth to & # 39; emerge from a green-green pineapple.
The palaeontologist Dr Phil Bell of the University of New Zealand in the nearby Armidale, who was over the investigation, said: "I remember Mike has shown my example and let me go to # 39 "But I wanted to try hard to keep my encouragement, it was so beautiful".
He said that he was looking at Lightning Ridge as a fossil resource all over the world because he has preserved several distinct Cretaceous animals.
"If these fossils were in rock, like those found in China and Mongolia, it would be the total finances," he said. "Unfortunately, the remains of fossils that we see are almost always part of a mining spoil, as they sit in a rock strata that is up to 30 meters below the ground. The mineral process will ; fracture of fossils in pieces – but on the other hand, we would not even see those items unless it was for mining. "
Jenni Brammall, paleontologist, gemmologist and Australian Opal Center manager in Lightning Ridge said the "jawbone" was a "very rare and unexpected".
She said: "This amazing little bit of the trout is 100 million years of new dinosaur and granite species."
The Weewarrasaurus jaw is now part of the Australian Opal Center collection, the most diverse public collection in the world of double fossils.
