在人们的印象中,中生代是恐龙独霸天下的时期,那时候哺乳动物都是像老鼠一样毫不起眼的小个子,生活在恐龙的阴影之下。事实并不尽然,通过新近对古生物化石的发现和分析,科学家们也大吃一惊,中生代时也有体型较大,拥有尖利牙齿,和恐龙争食、争地,甚至能吞食幼体恐龙的哺乳动物。这是中国科学院古脊椎与古人类研究所胡耀明、王元青和李传夔及华裔科学家孟津等的最新研究成果。一具动物头骨化石开始改变了科学家的观点,中生代哺乳动物并非都身小如鼠。
In people’s minds, the Mesozoic era was the period when dinosaurs dominated the world. At that time, mammals were all small, mouse-like people who lived in the shadow of dinosaurs. The facts are not always true. Scientists were also surprised by the recent discovery and analysis of paleontological fossils. In the Mesozoic era, they also had larger bodies, sharp teeth, and dinosaurs who fought for food and land and even devoured larvae. This is the latest research result of Hu Yaoming, Wang Yuanqing, and Li Chuanxi of the Institute of Ancient Vertebrate and Paleoanthropology of the Chinese Academy of Sciences and Meng Jin, a Chinese scientist. An animal skull fossil began to change scientists’ point of view. Not all Mesozoic mammals are small mice.
