At the base of the Valanginian a major discontinuity associated with one of the major transgressions of the Cretaceous is nominated as a candidate for the boundary between the Cretaceous and Jurassic systems. This surface has been identified in both platform and basinal domains, at the eastern edge of the North American continent and in the Middle East, as well as through the western edge of Africa and Europe.
