Stratigraphy
| Formation: | Kekexiongkuduke | ||||
| Stratigraphic resolution: | formation | ||||
| Stratigraphy comments: Except where otherwise stated, ref. 7624 uses Lower Silurian as equivalent to Llandovery, Middle Silurian as equivalent to Wenlock, and Upper Silurian as equivalent to Ludlow plus Pridoli. "This fauna was assigned [Wang Wu-yan 1979] to the Ludlow, although the faunal list does not provide very compelling evidence despite the faunas occurrence above beds assigned by them to the Wenlock." | |||||
