The Zhiluo Formation is a geological formation in China, it is also alternatively considered a geological group under the name Zhiluo Group (formerly known as the Chiloo Group). It dates to the Middle Jurassic. It consists of sandstone, mudstone and siltstone of varying colours. It has received scientific attention for its uranium ore bodies present in the lower part of the formation.[1] Fossil theropod tracks have been reported from the formation.[2] These were described from two footprints found in Jiaoping Coal Mine by C. C. Young in 1966 as Shensipus tungchuanensis. These were in 2015 suggested to belong to Anomoepus.[3]
