The results of the late Kansas work by Girty* and White are presented 
In tables giving the range of the fossil specie*. The vertical distribu- 
tion is extended upward beyond the highest rocks of Iowa and Missouri. 
Altogether, from the base of the productive coal measures in these 
states, from the bottom of the Des Moines series, through the Missourian 
series and the Oklahoman series, or to the top of the Marion formation 
in central Kansas, there are some 2,000 feet of strata. There are alter- 
nating limestone and shale formations which number about fifty. These 
25 limestones and 25 shales have received distinctive names. 
It is a well known fact that organic remains are abundant from the 
bottom to the top of the section. The remarkable feature of the Girty 
tables is that with few exceptions the fossils were obtained from only 
the limestone beds — the shales yielding few or no forms. In other 
words the fossils are practically in alternating formations. This alter- 
nation of limestones and shales is shown in the following list of forma- 
tions beginning at the top of the section.
