The Haifanggou Formation (also known as the Jiulongshan Formation) is a fossil-bearing rock deposit located near Daohugou village of Ningcheng County, in nner Mongolia, northeastern China.
The rocks consists of coarse conglomerates, sandstone, mudstone, and thin coal layers.
The formation dates from the Middle Jurassic.[1]
