19 (J The Upper Cretaceous Floras of the World 



This flora contains 20 Dakota species, 22 Earitan species, 19 Magothy 

 species, 8 Tuscaloosa species and 4 Black Creek species. There are 11 

 species common to the Perucer beds of Bohemia and Moravia, G to Nieder- 

 schcena, 7 to the European Turonian, 3 to Aachen and 3 to the West- 

 phalian Cretaceous (Campanian). Four have been identified in the 

 Montian of Europe. 



The large number of Atane species present (thirty-four) as well as the 

 numerous Dakota, Earitan and Magothy species preclude considering 

 the flora as young as, for example, the Laramie. It is singular if the 

 Patoot flora is younger than the Emscherian that it should have so much 

 more in common with the Cenomanian and Turonian floras than with the 

 extensive Lower (Campanian) and Upper (Maestrichtian) Aturian 

 floras so extensively developed in north Germany. On the other hand, the 

 four Montian species are not without significance. It is possible that 

 several horizons of the Upper Cretaceous are represented. 



The Atlantic Coastal Plain 

 marthas vineyard to the district of columbia 



This area includes traces of former Cretaceous sediments on the shores 

 of Massachusetts Bay; the remains of such sediments preserved in place 

 or for the most part in morainic material along the islands of the south 

 shore of New England and including Marthas Vineyard, Block Island, 

 and numerous localities throughout the extent of Long Island : Staten 

 Island ; and a belt of territory extending southwestward across New 

 Jersey, Delaware, and Maryland to the Potomac Eiver. 



The accessibility of these areas to large centers of scientific activity and 

 the economic importance and exploitation of the clay and sand areas of 

 the Amboy district in New Jersey have resulted in an enormous literature, 

 going back as early as the beginning of the eighteenth century and which 

 cannot be cited in a chapter like the present. Fossil plants from Marthas 

 Vineyard were figured by Edward Hitchcock as early as 1841, and Conrad 

 in 1869 described a Podozamites from the New Jersey Earitan. The chief 

 contributors to the paleobotany of this area have been Newberry, Hollick, 

 and the writer. Newberry's pioneer work related chiefly to the Amboy
