Stratigraphy
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. Collection from upper part of sequence. "Corals in toto [i.e., both middle and upper parts] indicate a Wenlock-Early Ludlow age span." Presumably the middle part would be Wenlock and the upper part Ludlow, but this is not entirely clear.
