An Undiscovered Bone Of Centrosaurus

In northern Alberta, Scientists says that they’ve discovered the uncovered largest dinosaur graveyard in the world so many fossils are found in the province.
A 2.3-square-kilometre bone bed containing thousands of bones belonging to a horned dinosaur called the centrosaurus which was found near Hilda, Alta., a community near the Saskatchewan border, according to David Eberth.He is a senior research assistant with the province's Royal Tyrrell Museum.
He said that the bone is looking very ugly. The bone bed is actually exposed, it's very patchy and exposed in outcrops along the beautiful landscapes along the South Saskatchewan River."In the late 1990s, the dino graveyard was actually discovered. The centrosaurus was same size as a cow, however, much dumber than a cow.

Dinosaurs Roaming Again On The Earth

      Dinosaurs are roaming back on the earth in a spectacular theatrical arena show,"walking with the dinosaurs".The show is arranged for the award function for BBC Television Series.It is now on tour in North America at Madison Square Garden in New York.
   Designers have worked with Internationally renowned  scientists to create 15 life-size dinosaurs, including the terror of the ancient terrain, Tyrannosaurus-rex!.It tells the story of their 200 million year domination of life,walk,roar on earth.
    The ripple of their skin to the glint in their eye,makes us to think that the dinosaurs really have returned!The recommended age for the show is from three to 93. The show has been carefully arranged  written and produced for the entire family, and there is peaceful environment.

A Dino With Grinding Mouth and Wrinkle Eyes

In University of Pennsylvania doctoral candidates and a team of paleontologists, has described a new species of Dinosaur  with an incomplete skeleton. It was found in western New Mexico. The new species, Jeyawati rugoculus was found from rocks that conserves a swampy forest ecosystem that found near the shore of a vast inland sea.It was found before 91 million years ago.

The specimen was kept under a Paleontological Resource. They  are used   by the U.S. Bureau of Land Management for the study  provided by the Paleontological Society, the Western Interior Paleontological Society and the University of Nebraska Undergraduate Creative Activity and Research Program.

The dinosaur, whose name describes to mean "grinding-mouth, wrinkle-eye," was most likely an herbivore that consumes the ferns and conifer trees found as fossils in the same rock layer. A basal hadrosauroid, the find has partial skull bones, several vertebrae and fragments of the ribs.
Jeyawati is a  type of the duck-billed hadrosaurs, which were abundant across the Northern Hemisphere for much of the Late Cretaceous Epoch, between 80 and 65 million years ago. Jeyawati has features of the teeth and jaws that preclude it from   a fully-fledged hadrosaur.

Dinosaur's Fossil information

     About 30-foot-tall Allosaurus skeleton have been displayed on the 900 Baseline Road building from 8:30 a.m. to noon. The free display is part of the Fossibilities program at the Wild Bear Mountain Ecology Center.

       In South Korea,a new type fossil dinosaur skin was discovered,which may help to find out the original dinosaur’s hides from skin-like features in rocks. 

       Two specimens of fossil dinosaur skin from   South Korea which has been identified  in a pile of rocks shriveled to from a road. The discover has  fully a  new kind of skin texture.
               Trailtrail Dinosaurs were the dominant terrestrial vertebrate animals for over 160 million years,   which is shown in figure.

Hot news about dinosaurs

In New Mexico , a skull was found and It was the skull of a new jumbo-sized genus and a new species of horned Dinosaurs .

 A close relative of Triceratops is Ojoceratops, a new dinosaur. More than 30 years the dinosaur was mistaken for another species . 

A  PhD student at Montana State University has found a skull of Dinosaur in the summer 0f 2005 in new mexico.

Mummified Dinosaurs emerges from stone tomb

For over two years, paleontologists have been chipping away at Dakota, a typical mummified duck-billed dinosaur that remains encased in a "stone tomb".

The Dinosaur, however, is almost 75 percent removed, revealing what appears to be fossilized skin, ligaments, tendons and, scientists hope, some fossilized internal organs.

Dakota is an Edmontosaurus that lived 65 million years before in what are now the North Dakota Badlands.

So far, 1,000 pounds of rock have been eradicated from the dinosaur by scientists who are using tools that look like dental instruments.

Dakota along with its tomb weighed more than 4 tons prior to the chiseling project began. The workers also utilize small, air-powered jackhammers, which fill the room with buzzing sound.

Amy Sakariassen, an archaeologist who works on the dinosaur part-time, said she is pleased if she can even successfully remove a coin-sized section of rock each day.

Dinosaur bones notify stories about northern Alaska

On a fine spring day about 70 million years before, a few dozen duck-billed Dinosaurs waded a channel of a great northern river. As they strode on two legs into the cloudy water, the man-size hadrosaurs had no thought how the sunshine was affecting the snowpack in the high mountains to the south.

A pulse of meltwater from the elevated country had swollen the river to much higher levels in the span of just a few hours. The dinosaurs ventured out too distant, lost their footing, struggled and drowned. The river carried the bodies of the beasts downstream, depositing them at what is at present a bend of the Colville River.

Researchers write that large floods in ancient Alaska may be in charge for the impressive deposits of Dinosaur bones they have found on Alaska's North Slope.

Like birds, big dinosaurs swallowed food whole

Unlike mammals, but exactly like birds, gigantic plant-eating Dinosaurs tended to swallow their food whole rather than bothering to pre-chew it, according to a team of German researchers.

The new theory could clarify why dinosaurs such as brontosaurus, which weighed up to 100 tons, had long necks and relatively tiny heads.

Until now, it was generally thought that birds swallow their food whole so as to decrease the time they are vulnerable to attack from predators. While that may be partly true, the latest evidence indicates that birds are simply following in the footsteps of their gigantic ancestors, the dinosaurs, who had to devour vast quantities of food as quick as possible just to stay alive, the scientists said.

Elephants and other large modern animals that eat a lot and chew require big heads to accommodate jaw muscles and molars. But a big head would not be necessary for a creature that swallowed down food without chewing.

Long necks would also have aided big dinosaurs get to food without moving from a particular spot — again saving time.

Dinosaur skull shape varied drastically during growth

University of Michigan paleontologists have asserted that long-necked sauropod Dinosaur, Diplodocus, went through drastic changes in skull shape during normal growth.

To reach the end, paleontologists John Whitlock and Jeffrey Wilson, along with Matthew Lamanna from the Carnegie Museum examined the skull of a juvenile sauropod dinosaur, rediscovered in the collections of Pittsburgh's Carnegie Museum of Natural History.

The discovering has been explained in the March issue of the Journal of Vertebrate Paleontology.

‘Adult sauropod skulls are exceptional, but juvenile skulls are even rarer,’ said Whitlock, a doctoral candidate in the U-M Museum of Paleontology. ‘What we do know about the skulls of sauropods like Diplodocus has been based completely on adults so far.’

Determining dinosaurs’ body temperature using isotopes

Scientific community is thrilled by a report that investigation will shortly reveal whether Dinosaurs were ectothermic or endothermic. The cause here is that scientists see in them a resemblance with both endothermic birds and mammals and ectothermic reptiles and amphibians.

American paleontologists reported about the development of innovative technology that helps to determine the body temperatures of animals by the isotopic analysis of biological apatite, basic mineral in fossilized remains.

The scientific journals of the West call the high accuracy of the innovative method into question since there is no possibility of going back a million years to measure a dinosaur’s temperature using a thermometer. The new method is depend on the analysis of rare heavy isotopes of carbon and oxygen in bones.

Scientists insist that they verified the method on a contemporary Indian elephant, a white rhinoceros and a crocodile in the River Nile. The temperatures determined from the teeth of these animals matches with that from traditional measurements. The consequences of a research into Fossil remains of the ancestors of rhinoceros and crocodiles that died 12 million years before were proved to be identical. This indicates these animals had similar temperatures.
