328 F\ REPORT OF PROGRESS. E. W. CLAYPOLE. 



The Hamilton Upper shale, (VIII.) 



This shale enters the township from Centre near Mans- 

 ville, and continues along the Little Buffalo Creek road to 

 the water-shed. It then follows the same road along the 

 headwater of the Great Buffalo, zigzags twice at the end of 

 the syncline and again north of Roseburg, and leaves the 

 township to enter Tuscarora. Numerous roadside exposures 

 may be met with, some of which yield fossils abundantly 

 and in good condition, especially Splrifera granulifera. 

 On the whole, the exposures of this shale in Saville town- 

 ship are as profitable to the palaeontologist as any in the 

 county. 



The Chemung group, (VIII.) 



This group, as in Juniata township, forms the south slope 

 and part of the summit of Middle ridge. Its beds are ex- 

 posed along most of the roads ascending it on that side but 

 few extensive fossiliferous exposures can be found. Curv- 

 ing round at the west from Middle ridge it leaves the town- 

 ship at the western end of Hominy ridge. The two, there- 

 fore, are really but one long continuous outcrop of the same 

 beds skirting the end of the syncline. 



The beds of this group need no lengthened description in 

 this township but present one interesting feature. They 

 here display a divergence from their type in the southeast 

 of the county in their upper portion by being more red and 

 sandy and contain fossils which I have not found in the 

 southern syncline. Some of the beds decidedly approach 

 the type of beds correspondingly situated in northern Penn- 

 sylvania, in Bradford county, for instance. The Mansfield 

 red beds which are there so distinct are indicated in Saville 

 township. This is also the only part of the county in which 

 I have found the common fossil of the Iron ore beds of the 

 north, Orammysia elliptica. Had time allowed a larger 

 fauna would probably have been collected. Other species, 

 rendering the parallel yet closer, will probably be found 

 when the material obtained is examined and studied.
