Lower sea levels in the Middle Cenomanian, by Jake M. HANCOCK [2003], CdG-NoG, Letter 2.
Abstract: It has been known since the 1970's that the relatively high sea levels during the Cenomanian in southern England and northern France were interrupted by a strong fall in sea level early in the Middle Cenomanian. This was a eustatic trough whose effects can be found not only in north-west Europe, but also from western Kazakhstan in central Asia to Texas, Colorado and South Dakota in the U.S.A.
