Stratigraphy
| Formation: | "Shihtienfeng" | ||||
| Stratigraphic resolution: | formation | ||||
| Stratigraphy comments: Since 1956 when the holotype specimen was found at Dongsheng, the Shih-Tien-Feng Formation has been subdivided into the Er-Ma-Ying, He-Shang-Gou, and Liu-Jia-Gou Formations (Li, 1983). Unfortunately the author does not state from which of the three new subdivisions the fossil actually comes (TL). The originally entered formational name >>Shih-Tien-Feng<< was replaced by the more common spelling >>Shihtienfeng<<. Additional note: The name "Shihtienfeng Formation" (= Shiqianfeng Fm.) is still used in more southerly areas of the Ordos Basin (see, e.g., PBDB colls. 78694 or 92907) (TL). | |||||
