Tennessee west of the river of that name is physiographically 
and geologically a part of the Atlantic Coastal Plain. The Upper 
Cretaceous deposits of Tennessee outcrop in a belt of considerable 
width which extends across the state from north to south im- 
mediately west of the Tennessee River. In McNairy and Hardin 
counties on the south this belt is about sixty-eight miles in width, 
but the beds become thinner or are overlapped by the Eocene to 
the northward so that in Henry County on the northern boundary 
the Cretaceous belt is only about ten miles in width. 
The Upper Cretaceous of Tennessee when compared with that 
of Alabama and Mississippi is seen to be much thinner. According 
to the nomenclature adopted for Tennessee} the sequence from 
the top downward is as follows:
