The Angola shale contains few fossils. In the beds exposed 

 along Cazenovia creek plant remains are numerous. The beds 

 immediately above the top of the Rhinestreet contain numerous 

 nodules of pyrite which appear to be casts of fossils. The 

 flattened concretions found in the middle of the formation at 

 Angola contain fossils of a few species. 



Shale of this formation has been used for the manufacture 

 of brick and other clay products. The Buffalo Sewer Pipe 

 Company has a plant on the Lake Shore Railway just west of 

 Angola which utilizes this shale. 



The Jewettvllle Brick Plant Number Two utilizes shale 

 probably of this formation. It is situated a mile southeast of 

 Orchard Park station on the Buffalo, Rochester and Pittsburgh 

 Railway.

The name Hanover shale has been applied to the upper 

 portion, 112 feet thick, of a mass of 280 feet of gray shales and 

 sandstones lying between the Rhinestreet shale below and the 

 Dunkirk black shale above. The lower 168 feet of these have 

 been given the name of Angola shale already described. 



The upper or Hanovtr shale was at first designated the 

 Silver Creek shale because of its outcrop at the village of Silver
