    Xinhua News Agency, Xi'an, November 1st, from Northwestern University research team learned that previously by archaeologists in The Long tooth cave in Luonan County, Shaanxi Province, scaly fossils, recently identified as about 350,000-270,000 years ago, the fossils of water snakes.
    According to Li Yongzheng, a senior engineer in the Department of Geology at Northwestern University, the fossils are two fossils, one of which is a snake spine fossil, about 3 mm long, and the other is a three-section connected snake spine fossil, which is about 10 mm long. The fossils are part of a 1996 excavation by the Shaanxi Archaeological Research Institute. Because the fossil was so small, it was difficult to tell what part of the animal it was.
