West River shale 



In these beds we find a return of the shale fauna beneath 

 (Genesee) with a few additional species. The distinctive char- 

 acters of the division are essentially lithologic. Its fossils are: 



Pterocbaenia fragilis Hall c

Embedded in these shales not far above the Genundewa 

 limestone is a thin and, over the region of this map, continuous 

 limestone which is a mass of the crinoid Melocrinus
