First winged mammals from the Jurassic period discovered
Two 160 million-year-old mammal fossils discovered in China show that the forerunners of mammals in the Jurassic Period evolved to glide and live in trees.
With long limbs, long hand and foot fingers, and wing-like membranes for tree-to-tree gliding, Maiopatagium furculiferumand Vilevolodon diplomylos are the oldest known gliders in the long history of early mammals.
