Large dinosaur fossil site found in SW China

Chinese paleontologists have discovered a large fossil site in southwest China's Chongqing city, according to a press conference held Wednesday by the city government.
More than 5,000 fossils have been excavated from a "fossil wall" in Pu'an Township, Yunyang County, since October last year, just a year after the site was spotted by a local farmer.
It is estimated that a large number of dinosaur fossils are buried at least 20 meters underground.

Sensitive faces helped dinosaurs eat, woo and take temperature, suggests study

Dinosaurs' faces might have been much more sensitive than previously thought, according to a University of Southampton study - helping them with everything from picking flesh from bones to wooing potential mates.
Experts used advanced X-ray and 3D imaging techniques at the University's -VIS X-Ray Imaging Centre to look inside the fossilised skull of Neovenator salerii - a large carnivorous land-based dinosaur found on the Isle of Wight, and currently housed in the Dinosaur Isle museum - and found evidence that it possessed an extremely sensitive snout of a kind previously only associated with aquatic feeders.

Fossil sheds light on 'Jurassic Park' dinosaurs

The fossil of a dinosaur that has been languishing in a museum for decades has been re-examined - and it turns out to be that of a new species.
Brachiosaurus, depicted in Jurassic Park, now has an early relative, providing clues to the evolution of some of the biggest creatures on Earth.
Scientists say the plant-eating dinosaur was longer than a double-decker bus and weighed 15,000kg.
Its remains were found in the 1930s in the Jura region of France.

Professors name dinosaur after digging up thousands of bones

University officials say they've named a dinosaur that they found hidden in Utah.
Brigham Young University professors have created a full picture of the sauropod from thousands of fossilized bones and published a paper Tuesday in the University of Michigan's Contributions from the Museum of Paleontology.
The creature has been named Moabosaurus because it was found near Moab. Like other sauropods, researchers say it was an herbivore with a long neck and tail and a small brain but it was much smaller, at 32 feet.

Major shake-up suggests dinosaurs may have 'UK origin'

The first dinosaurs may have originated in the Northern Hemisphere, possibly in an area that is now Britain.
This is one of the conclusions of the first detailed re-evaluation of the relationships between dinosaurs for 130 years.
It shows that the current theory of how dinosaurs evolved and where they came from may well be wrong.
This major shake-up of dinosaur theory is published in this weeks's edition of the journal Nature.

Possible dinosaur egg fossils found in Shaanxi

Possible dinosaur egg fossils were found at a road construction site in a village in Shangluo City, Northwest Chinas Shaanxi Province. Archeologists preliminarily found the objects could be dinosaur egg fossils, with two of the five objects found mostly intact. Local authorities have suspended construction at the site temporarily and asked experts to help confirm the findings.

'Startling' dinosaur protein discovery

Ancient proteins dating back 195 million years have been found inside a dinosaur bone.
The discovery pushes back the oldest evidence for preserved proteins by 100 million years.
Scientists have also found traces of a mineral that probably came from the blood of the early Jurassic dinosaur.
Soft tissues provide new insights into the biology of dinosaurs and how they evolved.

MSU scientist publishes dinosaur research linking bony cranial ornamentation to body size

Theropod dinosaurs with bony ornaments, like horns and crests, evolved to gigantic body sizes as much as 20 times faster than species without them, according to research by a Montana State University evolutionary biologist. These ornaments perform a wide variety of functions, the most important being social communication and competition for mates.
