The Zuoyun Formation is an Early Cretaceous (estimated Albian)[1] geologic formation in Shanxi Province, China.[2] Dinosaur fossils attributable to the genus level are known from this formation.[1] During the Early Cretaceous, the Zuoyun area was generally dominated by an arid subtropical environment. There was irregular alternation of arid and humid climate, during which catastrophic flooding resulted in thick proluvial fan conglomerate-mudstone deposits.[3]
