 It preserved a large, fur-covered patagium, extending not only between the limbs and tail, but also to the digits, "sandwiching" them.The limbs were proportionally longer than those of other Mesozoic mammals, fitting the standards in flying and gliding mammals, and the femur is uniquely specialised, allowing the leg to be extended laterally and remain steady during gliding.The tail is dorsoventrally flattened, and supports evidence of uropatagia in at least the proximal vertebrae.
