Chinese scientists discover new dinosaur unearthed in Inner Mongolia******
HOHHOT, Nov. 2 (Xinhua) -- Chinese paleontologists announced the discovery of a new dinosaur with a unique butterfly-shaped neural arch of the anteriormost dorsal vertebrae, which makes it distinguishable from other troodontids.。
The research team found its holotype in north China's Inner Mongolia Autonomous Region. The holotype consists of a nearly complete cranium, with a total length of 12 cm and fragmentary postcranial bones. Its body length reaches 1 m.。
Pei Rui, the researcher with the Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences, said the dinosaur, living in the upper Cretaceous period about 83 million to 70 million years ago, was in the subadult stage, which is the key time for both individual development and population evolution.。
The discovery is important for the study on biodiversity of land-living creatures and paleoenvironmental change in Northeast Asia in the Late Cretaceous, Pei added.。
The online version of the discovery was published on "Cretaceous Research" in October. Enditem。
Preview: Barca to be tested by Vallecano after Clasico defeat******
MADRID, Oct. 26 (Xinhua) -- FC Barcelona have another difficult game on Wednesday night when Ronald Koeman takes his side to the south of Madrid to play Rayo Vallecano.
Barca travel after the 2-1 defeat at home to bitter rivals Real Madrid on Sunday, which laid bare the club's current difficult situation and once again placed Koeman in the firing line for criticism and worse as a group of fans insulted him and kicked his car as he left the Camp Nou after the game.
The club has issued a statement criticizing the incident, but despite his apparent support for the coach, club president, Joan Laporta would find it difficult to retain the Dutchman in the wake of a defeat to the recently promoted side.
Koeman will still be without the injured Martin Braithwaite, Ronald Araujo and Pedri for the trip, with rumors that Pedri's recovery from a knee injury is going to take longer than at first expected.
However, the Barca coach will be at least content that Ansu Fati looks as if he has now fully recovered from his knee injury, while Kun Aguero is pushing for minutes after scoring his side's consolation goal on Sunday.
Oscar Mingueza is likely to drop out of the side with Sergino Dest dropping back to right back, while Sergi Roberto and Philippe Coutinho could also start in the Vallecas Stadium.
Although Rayo have lost two of their last three games, the team from the south of Madrid are still seventh in LaLiga, which is a reward for the adventurous attacking football they are playing under coach Andoni Iraola.
Proof of that was the way they fought back from 2-0 down away to Betis at the weekend, before finally succumbing to a late penalty. But players such as Isi Palison, Randy Nketa and the experienced Radamel Falcao will be a handful for a hard-pressed Barca defense and unless Barca can deal with their high pressure better than they did with Real Madrid's on Sunday, Koeman could be in trouble.
