Two gliding Euharamiyidan mammal fossils, dating back to the Jurassic Period at 164 million and 159 million years ago respectively, are shown at Bohai University in Jinzhou, Northeast China’s Liaoning province on November 14, 2017. The fossils were discovered at the beginning of 2014, and October 2015 successively in Nanshimen village of Qinglong county by scientists from Chinese and American institutions. The scientists have been restoring and analyzing the fossils over the past few years, and concluded that the discovery has proved the diversity of the ancient mammal species, which is of great value to the study of the evolution of the mammalian middle ear.
