Shishugou Formation

The Shishugou Formation (simplified Chinese: 石树沟组; traditional Chinese: 石樹溝組; pinyin: Shíshùgōu Zǔ) is a geological formation in Xinjiang, China.

Its strata date back to the Late Jurassic period. Dinosaur remains are among the fossils that have been recovered from the formation. The Shishugou Formation is considered one of the most phylogenetically and trophically diverse Middle to Late Jurassic theropod fauna.

The Wucaiwan Member, once considered a separate, underlying formation, is now considered the lowest unit of the Shishugou Formation.
