The credit for th£-first_lefi_/'ife)reeb'gnitib_.b{ the Cretaceous
age of any of the Coastal Plain deposits belongs to Vanuxem
and Morton. Together, in _82). t}my published a paper in the
Journal of the Philadelphia Academy, 1 in which the Coastal
Plain deposits are classified as follows:
Modern Alluvial.
Ancient Alluvial.
Tertiary,
C Lignite.
Secondary _ Mart.
Both Vanuxem and Morton punished subsequent papers, but
their chief interest, however, centered in the fossil remains of the
]_{Iarl.se/-ies, which they correlated with the Lower Chalk, or
Ferru_nous Sand formation of Europe.
In I832 Conrad divided the Coastal Plain into six formations,
i. e. :
Alluvium.
. Diluvium.
Gravier Coquillier, of Brong. Crag (mouth of the Potomac.)
Upper Marine, or Upper Tertiary (Peninsula of Maryland,
etc.)
Middle Tertiary, or London Clay and Calcaire grossier
(Ft. Washington, Claibor_e, etc.)
Lower Tertiary, or Plastic Clay (Bordentown, White
Hil% N. J.; Cape Sable, Md., etc.)
Li_ite, pyrite and amber are mentioned from the Plastic
Clay formation. This was the first classification which even
hinted at the true complexity of the Coastal Plain, and from
this time or_ward the latter has been treated not as a single, or,
at most, a few formations, but as a long series of deposits of
varied composition and age.
In I8352 and again in I842a Morton set forth his views on
the classification of the Cretaceous, dividing it into an Upper,
