Upper Cretaceous marine deposits from the Mid-Atlantic region of North America (Delaware, Maryland, and New Jersey) and the Maastricht area (southern Netherlands, and nearby Belgium and Gennany) are correlated across the Atlantic using a variety of macro invertebrates, nannofossils, and sequence stratigraphy. Four late Cretaceous Mid-Atlantic sequences, the Marshalltown, Englishtown, Merchantville, and Navesink, span the upper Santonian to lowennost Danian, and have direct correlatives in the Maastricht area. Correlations between the Mid-Atlantic and the Maastricht regions (respectively) are as follows: the upper Santonian to lower Campanian Merchantville and Matawan formations with the Achen and lower Vaals fonnations; the middle Campanian upper Englishtown F onnation with the upper Vaals F onnation; the uppermost middle Campanian to upper Campanian Marshalltown, Wenonah, and Mount Laurel fomlations with the lower Gulpen Fonnation; the Navesink and lower Severn fonnations with the middle Gulpen Fonnation; and the New Egypt and upper Severn fonnations with the upper Gulpen and Maastricht fonnations. Additionally, deposits of the Maastricht area also provide support for several proposed subdivisions in the Marshalltown and Navesink sequences. The correlations proposed here can serve to refine the biostratigraphy oflarge marine vertebrates known from both sides of the Atlantic.
