688 J. W. BEEDE BEDS OF APPALACHIAN AND WESTERN SECTIONS 



2. The horizon of the Ames limestone is probably no higher than the 

 top of the Oread limestone, and the top of the Conemaugh is at least as 

 low as the top of the Shawnee stage, and that the Neva limestone is as 

 high as the base of the Dunkard formation. 



3. That marked changes in the fauna set in at the base of the Schwag- 

 erina horizon (Neva limestone). 



4. In the formation below the Schwagerina horizon (Elmdale) only 

 transition plants are known which go over into the Permian of Europe 

 and America. 



5. In the first known plant horizon above the base of the Schwagerina 

 horizon (in the Wreford limestone) the flora has a decided Permian 

 aspect. 



6. The vertebrate faunas older than the Schwagerina horizon are 

 strongly Amphibian in character. 



7. That the known vertebrate faunas above this horizon are strongly 

 reptilian in character and they are even highly specialized. 



8. The oldest known red beds of the Appalachian and western interior 

 regions are almost equivalent in age, the latter apparently quite as old as 

 the former. 



9. The climatic conditions were essentially the same in both regions 

 throughout Pennsylvanian time.
