Chuanjie Formation
The Chuanjie Formation (simplified Chinese: 川街组; traditional Chinese: 川街組; pinyin: Chuānjiē Zǔ), is a geological formation in Yunnan, China. It dates back to the Middle Jurassic.[1] It was formerly referred to as being the lower member of the "Upper Lufeng" as opposed to the underlying "Lower Lufeng" now referred to as the Lufeng Formation. Tracks of theropods and sauropods,[2] as well as thyreophorans[3] are known from the formation.
