Maryland Geological Survey 109 



A somewhat similar problem presents itself in the presence of later 

 Cretaceous formations in New Jersey and their absence elsewhere along 

 the coastal border. Gradual transgression of first the Eocene and then 

 the Miocene, followed by the extensive cover of Pleistocene deposits, sug- 

 gests the possibility that deposits of equivalent age to the Eancocas and 

 Manasquan may exist farther to the eastward in Maryland and thence 

 southward to the Gulf. The only evidence that has ever been introduced 

 in support of this view is the questionable determination of Terebratula 

 harlani from the well boring at Old Point Comfort. It would not be at 

 all surprising if deposits of this and even Manasquan age were found in 

 deep-well borings along the continent border. A discovery of diagnostic 

 fossils of these horizons would add a notable chapter to the history of 

 the Atlantic Coastal Plain. 



The following table presents in tentative form the relations of the 

 Upper Cretaceous deposits in the Atlantic and eastern Gulf areas.
