The species is revealed by a fossil find in northeastern China, which pushes the known history of mammalian gliding or flying back by more than 75 million years.
The creature may have even beaten birds into the air. Like today's flying squirrels, it stretched a furry membrane between its limbs to provide an airfoil for gliding after it jumped from a tree. But it's not related to anything living today.
Scientists don't know exactly when the animal lived. Its remains could be anywhere from 130 million to 164 million years old, said Jin Meng of the American Museum of Natural History. He and colleagues from Beijing report the Inner Mongolia fossil discovery in Thursday's issue of the journal Nature.
So it's clearly older than the 51 million-year-old bat that used to be the oldest evidence of flying or gliding in a mammal. And it has a chance of preceding the earliest known bird, Archaeopteryx, which flew about 150 million
years ago.

I cant wait to tell Thing 1
That mammals may have flown/glided longer than birds! This should be something that he can stump his teacher with.
