Toutunhe Formation
The Toutunhe Formation is a Middle Jurassic geological formation in China. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation.[1] The lower portion of the formation consists of grey to reddish mudstone with medium to coarse grained cross bedded sandstone, while the upper portion consists primarily of brown-red-purple mudstone, interbedded with fine to medium grained laminated sandstone.[2]
