Also known as (Shih-Tien-Feng Formation); Hantai Valley

Where: Nei Mongol, China (39.8° N, 110.0° E: paleocoordinates 38.4° N, 88.5° E)

• coordinate based on nearby landmark

When: "Shihtienfeng" Formation, Early/Lower Triassic (252.2 - 247.2 Ma)

• 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).
