Lithostratigraphical correlation: Equates with a variable interval (depending on how Rowe defined the top of the underlying M. cortestudinarium Zone), from the top of the Lewes Nodular Chalk Formation/within the basal Seaford Chalk Formation to the top of the Seaford Chalk Formation of southern England.
