THE PLEISTOCENE FAUNA

The basis of correlation of the several formations of the Maryland re- 

 gion with those of other areas on physical grounds has been fully dis- 

 cussed in the earlier pages of this monograph and does not need to be 

 restated here. The evidence from the fossils, as far as available, bears 

 out the conclusions there obtained. Unfortunately the number of locali- 

 ties at which plant and animal remains occur is not large, although they 

 are fairly well distributed. The fossils collected come entirely from 

 the Pleistocene. None have been found in the Pliocene of Maryland. 



Local Interpretation. 



Fossil plants have been found in all three of the formations of the 

 Pleistocene, although well defined remains have been found only in the 

 Talbot and Sunderland, while the animal remains are confined to the 

 latest or Talbot formation. It is significant, however, that the animal re- 

 mains of distinctly marine origin occur at widely scattered points, and 

 far from the region of marine sedimentation of the present da}*". The 

 highly f ossilif erous localities at Wailes Bluff near Cornfield Harbor at the 

 mouth of the Potomac river, and at Federalsburg on the ISTanjemoy river 

 near the center of the Eastern Shore of Maryland are highly typical il-
