They still retain two pairs of relatively long and separate clawed fingers with a thick, short thumb; however, they possess well-developed flight structures, and the uncinate processes help to reinforce the rib cage. Their claws and toes are long and robust, while the legs are relatively short. Overall, their ability to fly and perch is exceptionally complex for a land-dwelling animal. The Longipteryx fossil comes from the old collection of an old collector. We have carefully sorted it out. The bones of this fossil are quite well preserved, and the texture of the bones can also be seen. We use an air pen to show the original appearance of the skeleton and feather imprints. This birds is the key to linking the evolution of birds and dinosaurs. Matrix: 20*19.3*2.2 cm, Body: 12 cm
