The Tugulu Group (simplified Chinese: 吐谷鲁群; traditional Chinese: 吐谷魯群; pinyin: Tǔgǔlǔ Qún) is a geological Group in Xinjiang, China whose strata date back to the Early Cretaceous. Dinosaur skeletal remains and footprints are among the fossils that have been recovered from the formation.[1][2][3][4]
