The primary standard for the Oxfordian–Kimmeridgian boundary is the base of the Sub-Boreal Baylei ammonite Zone, which corresponds to the base of the Boreal Bauhini Zone as recognized in the proposed GSSP section at Staffin Bay, Scotland. New data from the Sub-Mediterranean succession indicate that the boundary in question may be recognized fairly low within the so-called “Sub-Mediterranean upper Oxfordian”, not far from the boundary of the Hypselum (Semiarmatum) Subzone/Zone and the Bimammatum Subzone/Zone. This improves the detailed correlation between a large part of the “Sub-Mediterranean upper Oxfordian” and a lower part of the Boreal/Sub-Boreal lower Kimmeridgian, which would result in a change in the position of the Oxfordian–Kimmeridgian boundary in Sub-Mediterranean–Mediterranean successions.
