The thinning-out of these formations can probably be more clearly 
shown graphically. The sections that have just been described are 
grouped in the two accompanying figures, and follow each other 
consecutively. 
Several of the fossils collected at Irvine and also at Indian Fields 
when compared with those from the base of the Bedford at Columbus, 
Ohio, prove to be the same species. Of these Macrodon hamiltoniae 
is the most abundant one common to both fields. This paleontologi- 
cal confirmation of the conclusion reached by a lithological study is 
surely gratifying. 
It may be argued from this that the thin argillaceous horizon should 
be referred to the base of the Bedford rather than to the Bedford-
