Bulletin, geologic series 52

One of the most controversial geological problems in New Jersey is that relating to the age and correlation of the two uppermost greensand beds and the intervening sandy formation-the Vincentown--which outcrop in a relatively narrow belt of the Coastal Plain between Salem and Long Branch. Though they have received much study, authorities have differed as to whether they belong in the Upper Cretaceous of late 11esozoic age, or the Eocene (and Paleocene?) of early Tertiary age. It is the purpose of the present paper to make an analysis of the Cretaceous and Tertiary relationships of the bryozoa of the Vincentown formation, and to weigh their evidence against that of the rest of the fauna, together with such physical evidence as has been obtained
