Jianchang (Chinese: 建昌; pinyin: Jiànchāng) is a county of Huludao City in the southwest of Liaoning province, China. It is the largest division of Huludao, with an area of 3,195 square kilometres (1,234 sq mi),[1] and population of 600,000[when?], located in mountainous terrain 85 kilometres (53 mi) west of that city, serviced by China National Highway 306. The Weizhangzi–Tashan railway also passes through the County.[2]
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]
