430 A. W. GRABAU THE SHERBURNE SANDSTONE 



Tropidoleptus carinatus (r) 

 Spirifer sp. (rr) 



Nuculites oblongatus (rr) 



These clearly belong in the horizon of the Sherburne sandstone. In the 

 Panther Creek valley, southwest of West Fulton, coarse shales with an 

 abundant Hamilton fauna occur about 100 feet or a little more below 

 shales carrying the Ithaca fauna with Spirifer mesastrialis. These ap- 

 parently are also of the horizon of the Sherburne sandstone. On the 

 Mill Creek highway, in arenaceous shales 215 feet below beds carrying the 

 Ithaca fauna, Prosser found^^ 



1. Tropidolei)tus carinatus a 



2. Ghonetes coronatus rr 



3. Amhoccelia uml)onata rr 



4. Camarotoechia congregata c 



5. 0. cf. stevensi rr 



6. Cephalopod fragment rr 



This though a Hamilton fauna is clearly in the rocks of the Sherburne, 

 though perhaps in the lower part at West Blenheim, in rocks the top of 

 the Sherburne or the base of the Ithaca (M^ of Prosser), Prosser found 

 the following fauna.^^ 



1. Spirifer mucronatus (c) 



2. Ghonetes setigera (c) 



3. Tropidoleptus carinatus (r) 



4. Leda diver sa (rr) 



5. Orthoyiota undulata (rr) 



6. ScMzodus appressus (rr) 



7. OrMculoidea sp. (rr) 



This is a Hamilton fauna. Forty feet lower, in the bluish shales (M^), 

 Prosser found 



1. Liorhynchus multicosta (young) c 



2. Goleolus tenuicinctum ? rr 



Northwest of Franklinton, in Broome township, Schoharie County, are 

 greenish shales, 50 feet below mottled red and green shales and 115 feet 

 below red sandstones of the Oneonta type. These shales contain a Ham- 

 ilton fauna, while two loose specimens of Spirifer mesastrialis were found 

 near by, probably introduced from elsewhere. The fauna in place com- 

 prises, according to Prosser,^^ 



1. Spirifer mucronatus (a) 



2. Spirifer granulosus ? (c)
