滑翔飞行在哺乳动物演化过程中曾多次独立出现,但滑翔的直接化石证据非常罕见,此前科学家还没有发现中生代滑翔哺乳动物的证据。美国纽约自然历史博物馆孟津与中科院古脊椎动物与古人类研究所胡耀明等,研究了发现于内蒙古宁城地区中生代地层中(1.25亿年前)的一件几乎完整的哺乳动物化石。该种哺乳动物体长12～14cm,具有高度特化的以昆虫为食的牙齿和可以用于飞行的翼膜。该种动物代表了哺乳动物的一个新目,研究人员将其命名为远古翔
Gliding flights have appeared independently many times during mammalian evolution, but direct fossil evidence of gliding is rare, as evidence of Mesozoic gliding mammals has not been found before. Mengjin, New York’s Museum of Natural History, and Hu Yaoming, Institute of Vertebrate Paleontology and Paleoanthropology, Chinese Academy of Sciences, studied an almost complete mammalian fossil found in the Mesozoic strata in Ningcheng, Inner Mongolia (125 million years ago). The mammal, 12-14 cm in length, has highly specialized insect-eaten teeth and wings that can be used for flying. The animal represents a new breed of mammals, and researchers name it ancient glory
