DEc. 4, 1923 BERRY: LOWER CRETACEOUS OF ALABAMA 435 
As can be seen from the accompanying figures, the balance of the 
material is very incomplete. The tentative determinations which it 
has been possible to make are given in the explanation of these figures. 
The ranges of the species with which the Alabama specimens have 
been compared may be given briefly in tabular form as follows: 
‘The wide range, and the uncertainty of identification of these forms 
in the present collection, rob them of any certainty for purposes of 
precise correlation, but as none of them suggests any late Lower 
Cretaceous species known to the writer they are entitled to some 
weight, and as all of them have been found in the known Tuscaloosa 
formation of Alabama, and as one of the species seems to be positively 
identified, it would seem that the plant-bearing beds at Old Fort 
Decatur are of about the age of the Tuscaloosa formation of western 
central Alabama.
