It was found in 2000 at Lujiatun near Beipiao
City, Liaoning Province.
Oil shale in Longkou mine has the highest oil content; making about 14%, while Beipiao oil shale has the lowest oil content, which remains below 5%.
Because of low oil content (approximately 5%), the only suitable technology for Beipiao oil shale is Fushun retort technology.
Recently, many well-preserved specimens of the compression fossils from the Middle Jurassic Jiulongshan Formation in Daohugou Village, Ningcheng County, Inner Mongolia and the Upper Jurassic-Lower Cretaceous Yixian Formation in Huangbanjigou, Chaomidian Village, Shangyuan Township, Beipiao
City, Liaoning Province in Northeastern China were collected.
The northernmost locality where we have collected this scorpion is Beipiao
Li's story began seven years ago, in the city of Beipiao
when a county road maintenance officer manager driving a three-wheeler struck her husband's motorcycle and killed him.
The site, near the village of Beipiao
in Liaoning province in northeastern China was discovered by a local farmer who realized the potential scientific value of a fossil he found, which looked as much like a bird as a dinosaur, and which seemed to have a feathery crest - perhaps some form of primitive feathers or fur.
