Have dragons in their folklore and art:

BEIJING: Fossil findings of an ancient arboreal lizard in northeastern China's Liaoning province indicate that the reptile could glide through air using a membrane it could stretch across its elongated ribs.

The scientists found that reptile's gliding membrane, which is called “patagium,” is stretched across eight elongated dorsal ribs. When it is fully expanded, it would have spanned about 4.5 inches. The reptile had curved claws helping it to stay on treetops and then launch itself into the air. The scientists believe it could probably glide a longer distance than the modern-day flying lizards.
