300 Berry: MESOZOIC FLORA OF ATLANTIC COASTAL PLAIN 
Age of the Raritan——In a paper published in 1910 after a 
detailed study of the Raritan flora as typically developed in New 
Jersey the writer! showed that in terms of the European section it 
was unquestionably of Cenomanian age. The present study has 
only confirmed this conclusion, which is emphasized here since the 
late Professor Ward as well as some European paleobotanists have 
considered the Raritan as of Albian age while on the other hand 
certain American invertebrate paleontologists have held that it 
was even younger than Cenomanian. 
Age of the Magothy.—The Magothy flora from its resemblance 
to that of the underlying Raritan has also been considered to be 
of Cenomanian age although the writer? has more than once 
suggested that it represented the Turonian stage. The paleo- 
botanical studies carried on by the writer during the past eight | 
years and covering the coastal plain from New York to Texas 
completely confirm this supposition. In preparation for the 
Maryland report the Upper Cretaceous floras of Europe were all 
restudied in the light of the most recent stratigraphic and paleon- 
tologic work in France, Germany, Bohemia, etc. Detailed com- 
parisons have shown that no less than six of the Magothy species 
are known from the European Turonian, while several additional 
are represented in the two areas by closely related forms, so that 
the Turonian age of the Magothy may be regarded as established. 
With regard to the overlying Matawan formation, since it has an 
abundant fauna any statements regarding its age may be post- 
poned for the present, although it is interesting to know that 
several invertebrate paleontologists have correlated it also with 
the Turonian, a correlation that receives some measure of support 
from a study of the floras. 
All of the forms mentioned on the preceding pages will be 
fully described and figured in the forthcoming volume of the 
Maryland Geological Survey, in which will also be found the results 
of detailed studies by various authors of the genesis of the sedi- 
ments, the faunas, ecology, correlation and local geology.
