formations to the north, with the Woodbine sand of southern Texas, 

 and with the Dakota sandstone of the western interior. The Eutaw 

 flora closely resembles the floras of the Black Creek and Magothy 

 formations of the Atlantic Coastal Plain. It cannot be closely related 

 to any of the western floras, but since it is decidedly older than the 

 Montana flora the Eutaw formation may be considered to be syn- 

 chronous with part of the Dakota and with the Colorado series. The 

 flora of the lower part of the Ripley is related closely to those of the 

 Black Creek, Magothy, Tuscaloosa, and Raritan formations, while that 

 of the upper part shows little relation to any of the earher Cretaceous 

 floras.
