80 C. W. Honess — Stanley Shale of OMaJioma, 



At no other horizon in the entire Stanley, excepting the 

 tuff, is there so coarse a material. 



Higher in the Stanley where the plant horizons were 

 found, and in the Jackfork sandstones above, the vegetal 

 remains occur in thin beds charged with small twigs and 

 other small plant fragments, and also as scattered indi- 

 vidual specimens. The latter are usually large, pieces of 

 limbs and logs, but in all cases are macerated and eroded 

 fragments — materials, it appears, which have been floated 

 down stream from land areas to the south and southeast 

 and out upon the delta to the north where they were en- 

 gulfed in the sands.
