The Qingshan Group (simplified Chinese: 青山组; traditional Chinese: 青山組; pinyin: Qīngshān Zǔ) is a geological groupinShandong, China, whose strata date back to the BarremiantoAlbian stages of the Early Cretaceous. The group contains the Doushan Formation.^[1] Dinosaur remains are among the fossils that have been recovered from the formation.^[2]
