Oldest winged mammals found to have lived in dinosaur era
Scientists have discovered two 160-million-year-old fossils in China, identified as the oldest known winged mammals. The creatures lived during the Jurassic Period and evolved to glide and live on trees, 100 million years before modern mammal fliers. The ability to glide between trees allowed the ancient animals to find food that was inaccessible to other land animals, researchers said.
