Late Jurassic

The Late Jurassic is the third epoch of the Jurassic Period, and it spans the geologic time from 161.2 ± 4.0 to 145.5 ± 4.0 million years ago , which is preserved in Upper Jurassic strata. In European lithostratigraphy, the name "Malm" indicates rocks of Late Jurassic age...

 period. Dinosaur remains are among the fossils that have been recovered from the formation.

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

Ornithischians

Undescribed stegosaur is present in the Wucaiwan member. Undescribed ornithopod is present in the Wucaiwan member. Undescribed ankylosaurs present in both upper Shishugou and Wucaiwan members.
