Near the border with Hebei province lies the Jianchang Longtan Grand Canyon, home to wide variety of plants and animals. In 2009 a Troodontid dinosaur fossil with feathers was discovered in Jianchang. It is the earliest known such fossil and provides evidence for the link between dinosaurs and birds.[3] Also found here, in Jiufotang Formation rocks, was the early modern bird Schizooura.[4]
