NO. 5 PRE-DEVONIAN PALEOZOIC FORMATIONS 



The series is divided as follows (p. 15 D) : 



193 



" The fossils of the BanfT limestone show both Devonian and Car- 

 boniferous forms" (p. 19 D.) 



" The fossils of the Intermediate limestone are usually badly pre- 

 served and consist mainly of almost structureless corals." (P. 21 D. ) 



Dr. D. B. Dowling in 1907^ refers the Upper Banff shale to the 

 Permo Triassic and ])ro]XJses the name Rocky Moimtain ([uartzite 

 for the " fine grained sandstones " of the lower portions of McCon- 

 nell's Upper BanfY shale. This formation and the Upper BaniT lime- 

 stone. Power Banff shale, and Power Panff limestone, are referred 

 to the Carboniferous. 



The " Intermediate series " is referred to the Devonian. 



In 1913 Dr.- H. W. Shimer published the results of his study of 

 the Banff series and tabulated the formations as follows:^ 



.Shimer's reference of the Lower Banfif limestone and Intermediate 

 limestone to the Devonian was based on the fossils found in them. 



In 1914 Dr. J. A. Allan followed Shimer, except that he added 

 a lower limestone series, the Sawback limestone, to the base of the 

 Devonian.' 



Messrs. Kindle and Burling, in 1916, referred the " Intermediate 

 limestone " to the Devonian, and Allan's Sawback limestone to the 

 Cambrian.^
