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 [faunal] list suggests a Late Llandovery-Ludlow age range....Wang Wu-yan and others (1979) placed the formation in the Upper Silurian."
