A dinosaur with long display tail feathers

Abizarre bird-like dinosaur recently discovered by paleontologists with the CAS Institute of .Vertebrate Paleontology and Paleoanthropology（IVPP） has rekindled interest in the origin and early evolution of birds. This newly described species, which slightly preceded Archaeopteryx in geological time （around 150-145 million years ago）, surprises its discoverers with an unexpected combination of characteristics from different clades of theropod dinosaurs and some primitive birds. Most strikingly, italso sported two pairs of long primitive feathers on the tail.     

Ovarian follicles shed new light on dinosaur reproduction during the transition towards birds

<正>The reproductive systems of living archosaurs,crocodilians and birds are very diferent;the derived features present in birds are inferred to have evolved within the derived archosaur group,Dinosauria,which includes Aves(the common ancestor of Archaeopteryx+living birds)as a member of the derived theropod clade,Maniraptora.Compared to Aves,crocodilians have two ovaries,prolonged folliculogenesis(maturation

A tale of a 'middle' tail

<正>Zhongornis refers to a‘middle’or‘intermediate’bird because its tail was claimed to be transitional between primitive birds with a long bony tail(such as Archaeopteryx and Jeholornis)and those with a short tail ending in a fused tip called the pygostyle(such as Confuciusornis)[1].his inding is signiicant,as it appeared to ill a‘gap’at a critical stage     

A New "Missing Link" in Dinosaur's Evolution Found

A group of paleontologists from China, the United States and Canada have made new progress in tracking down the process of the evolution of smallsized dinosaurs and the origin of birds through intensive analysis of the fossils of a newly found dinosaur,Sinovenator, a close relative of birds. In a letter published in the Feb.14 issue of Nature, dinosaur expert Dr. Xu Xing at CAS Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) and his coworkers reveal some interesting phenomena in the process of the evolution of dinosaurs towards birds.

Cultural Conflicts and Compatibility between the East and the West in The Joy Luck Club

Via a study of The Joy Luck Club, Amy Tan＇s first effort, this essay discusses the cultural conflicts and compatibiliry between the East and the West as manifested by the conflicts and compatibility between two generations of Chinese Americans in the novel. The paper argues that different living environments, different cultural heritages of the East and the West as well as different values are the main causes of the mother-daughter conflicts in the novel. The paper concludes that these causes could also be regarded as the root of the cultural conflicts between the East and the West in general. More importantly, after a series of efforts, the two generations are in harmony, which stands for the cultural compatibility between the East and the West.
