The Kelhead Fossils. 



and the great abundance of marine fossils — Brachiopoda and 

 Cephalopoda — indicate deep sea conditions with clear water. 

 In this respect the horizon of the Kelhead Limestones is in com- 

 plete agreement with its English contemporaries. Yet as we 

 leave Cumberland and travel northward the limestones dwindle 

 in thickness, and are split up by beds of sandstone and shale. 

 The sandstones of Woodcockair and elsewhere prove that shallow- 

 water conditions prevailed both before and after the deep-sea 

 limestones of Kelhead. From the thickening out of these shore 

 deposits it is evident that the land lay towards the north of this 

 Carboniferous Ocean.
