THE KIMMSWICK AND PLATTIN LIMESTONES

ated with some form of Maclurites, but H or motoma major is 
much more common in the immediately overlying strata. The 
total thickness of strata here involved is 25 feet. The strata in 
which Hormotoma major is abundant are well exposed at locality 
6 on the W. Z. Zink farm, in the northeastern part of section 22. 
The rock here often weathers into coarse grained slabs with 
tortuous channels on top, and with more or less irregular cavities 
along the exposed margins. This coarse grained limestone is 15 
feet thick, and is overlaid at locality 7 by a fine grained, richly 
fossiliferous limestone layer, about one foot thick, overlaid by 
about 9 or 10 feet of similar fine grained rock, but with very 
few fossils beyond a single siphuncle of Endoceras and several 
specimens of Streptelasma corniculum. The Kimmswick lime- 
stone is overlaid here by 5 feet of yellowish clay shale of unde- 
termined age.
