InGen Database Description
The Lower Lufeng Series (also known as the Lower Lufeng Formation) is found in Yunnan, China. It consists of two units of Dull Purplish Beds and Dark Red Beds, dating to the Hettangian and Sinemurian stages of the Early Jurassic, 201 and 199 million years ago respectively.
The first dinosaur fossils were discovered here in 1938 by geologist Bian Meinian and technician Wang Cunyi. In 2004, the area became listed as China's National Geopark. It was then opened for visitors in 2008.
The sediments formed an alluvial plain of sandstone and mudstone.
In 2008 the first dinosaur footprints in the formation were discovered near the village of Yaohzan. Since then other footprints have been discovered in the locality.
Finds such as crurotarsi, tritylodont, crocodylomorph and mammaliaforme fossils have been recovered.
