Toutunhe Formation
Introduction The '''Toutunhe Formation''' is a Late Jurassic geological formation in China, specifically dating to the Oxfordian and Kimmeridgian stages. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation. 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.
