Time
| Period: | Jurassic | Epoch: | Early/Lower Jurassic |
| Stage: | Sinemurian | 10 m.y. bin: | Jurassic 1 |

| Age range of interval: | 199.50000 - 192.90000 m.y. ago |
Stratigraphy
| Formation: | Lufeng | Member: | Zhangjia'ao | ||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: The Lufeng Formation has been divided into lower dark/dull purple beds (= Shawan Member) and upper dark/deep red beds (= Zhangjiawa Member). Luo & Wu (1994: In the Shadow of the Dinosaurs, pp. 251–270) argue on the basis of vertebrate biostratigraphy for a probable Sinemurian age for the Zhangjiawa Member and a Hettangian age for the Shawan Member. | |||||
