Competitor T-rex Found in Australia
Published by Such as Australia has its own ecosystem. Typical of animals that live there are hard to find elsewhere. In addition to koalas and kangaroos, scientists found small fragments of dinosaur bones.
Ceratosaurus, Competitor T-rex Small Sized
This discovery led the new theory the dinosaurs that inhabit Australia together with the rest of the world.
Paleontologist Erich Fitzgerald stated fossil measuring 2.5 inch wrist bone was found in the SanRemo area of Victoria, Melbourne, Australia. The discovery of amateur paleontologists in 2009 it changed its way of thinking about the spread of the dinosaurs in the world.
The bones came from a known carnivorous species named ceratosaurus. These animals livedin Australia since 125 million years ago. Fitzgerald said the bone, indicating no predators other than Tyrannosaurus rex and allosaurs who had known earlier. Two predatory dinosaurswere also found in Australia.
“Dinosaurs are not as weird as we see modern koala and kangaroo on a global scale,” saidFitzgerald told AFP. “In contrast to modern animals we see in Australia, meat-eating dinosaurs in Australia represent a group spread around the world before the continents separated,” he said as quoted by Dailymail.co.uk.
Ceratosaurus was a carnivorous dinosaur is small. He could grow to as high as one to two meters.
Australia used to be a part of the Gondwana super continent that broke out in 80 to 130 million years ago. Australia separated from the others and dragged to the south. The otherpart to Antarctica and India.
“This isolation was instrumental in the formation of the dinosaur fauna in Australia,” said Fitzgerald.
Ceratosaurus and other findings indicate several groups of dinosaurs living in Australia. The dinosaur lived during the Jurassic. At 170 million years agodinosaurs were able to walk across two continents.
“Until now, the dinosaurs were mysteriously absent from Australia. But, now we can confirm the global distribution reach this area,” he added.
Detected traces of dinosaurs in Australia is difficult for several reasons. This huge continent which does not have many paleontologists are investigating.
When dinosaurs ruled the world, Australia closed shallow water. This condition causes the bones of storage is not as good in the dry climate.
This region also has a bit of mountain formation in the last few hundred years. This formation helps stir the surface and showed the bone to his hunters.
