80 THE COASTAL PLAIN OF NORTH CAROLINA.

The oldest, for which he proposes the name “Cape Fear” formation,
is correlated approximately with the Patuxent formation of Virginia.
For the next younger division, which is correlated provisionally with
the Tuscaloosa formation of Alabama, the name “Bladen” formation is
proposed. The youngest division is correlated with the Ripley of the
Gulf region, and the name “Ripley” formation is employed to designate
it. The names “Cape Fear,’ “Bladen,” and “Ripley” correspond re-
spectively to the names Patuxent, Black Creek, and Peedee as used in
the present report.

During the same year two important contributions were made by
E. W. Berry, relating to collections of fossil plants made by himself
and Stephenson from the “Bladen” formation during the two preceding
years. Lists are given, a number of new species are described and
figured, and the significance of the flora is discussed. In the first of
these papers®? he discusses the age of the plant-bearing beds as follows:

Because of their geographical position these beds should be provisionally cor-
related with the Tuscaloosa formation of Alabama; with this reservation, how-
ever, that the Tuscaloosa flora, as far as it is known, coincides with that of the
Raritan. Lithologically these North Carolina beds are much more like the
Magothy of New Jersey, Delaware, and Maryland than they are like the
Raritan, and it seems probable that when the problem has been worked out for
the whole Coastal Plain it will be found that the Tuscaloosa formation of
Alabama as a whole includes sediments of older Potomac, Raritan, and Magothy
age, while what is here called the Tuscaloosa formation in Nortiv Carolina,
already differentiated from the older Potomac, includes phases corresponding
to both the Raritan and Magothy formations of the more northern portions of

the Coastal Plain and to the upper Tuscaloosa and Eutaw formations of the
Gulf region.

In the second,?® diseussing the broader significance of the “Bladen”
flora, he says:

The remarkable flora, of a comparative modern aspect which seems to have
evolved in the Arctic region, and which migrated southward over eastern North
America during the Mid-Cretaceous, has been discovered at a large number of
localities during the last decade. Originally described by Oswald Heer from

the west coast of Greenland, it is now known from Massachusetts, the southern ~ a

pe England islands from Martha’s Vineyard to Brooklyn, from Staten Is-
and, and from the Raritan and Magothy formations of New Jersey, Delaware,
and Maryland. From Maryland southward there has been a long break in the
ae plants having been known from the Potomac to the Chattahoochee,

ra ance of about 800 miles. It is the purpose of the following brief note

to partially bridge over this intervening area and record this Mid-Cretaceous
flora from both North and South Carolina. }
