The Maryland Eocene is regarded as " nearly equal to that of the Thanet sands of 

 England and the Bracheux sand of the Paris Basin, or of the English Boguor rock 

 (London Clay >." It is also correlated with deposits near the base of the •' Buhrstone " 

 or possibly even the " Eolignitic " of the Gulf.
