Stratigraphy
| Formation: | Ermaying | Member: | Lower | ||
| Stratigraphic resolution: | group of beds | ||||
| Stratigraphy comments: Cow & Sun (1957) give the age of the fossil-bearing bed as "Triassic". Li (1989, tab. 4) says that "Paoteodon huanghoensis" is from the "Lower Ermaying Fm., Early Triassic".
The lower Ermaying Formation is of probable early Anisian age (e.g. Fröbisch 2009: Earth-Science Reviews 95, 119-157). It overlies the Heshanggou Formation of inferred Olenekian to earliest Anisian age, and underlies the upper Ermaying Formation of inferred Anisian age. The presence of the dicynodont Kannemeyeria within the lower Ermaying suggests correlation with Cynognathus Assemblage Zone Subzone B of South Africa, which is of early Anisian age. | |||||
