Fossils from Gastlecliff. 



The collections in this locality were made in the marine clifEs over a 

 distance of two miles from the Gastlecliff end. The rocks are everywhere 

 blue clay, or " papa," which, however, has a tendency to become more 

 sandy as the strata rise in the face of the cliff when they are followed to the 

 northward. This probably indicates that the water became rather more 

 shallow in this direction — a conclusion which is supported by the very 

 nature of the mollusca that are found in them as they are followed 

 northwards.
