Picture provided by the Nanjing Institute of Geology and Paleontology under the Chinese Academy of Sciences shows the morphology structure of the Chimerarachne. Two teams of Chinese scientists have begun study of a species of spider with a long tail, which is found in amber at least 100 million years old. The Chimerarachne found in Myanmar fills a gap in the evolution of the spiders. (Xinhua)
