lo Calciferous of the Mohawk Valley laa 



Conclusion 



The Ft. Hunter fauna is, as far as our present knowledge 

 goes, an isolated one, bearing a resemblance to both the Point 

 Levis fauna* and that of the Lake Chaniplain Calciferousf. As 

 one would expect from the geographical position of these locali- 

 ties, it is more closely related to that of the Lake Champlain re- 

 gion. It is remarkable that the geographical distribution should 

 show such wide diiferences in the faunas of these localities and 

 that of Rockdale, N. Y. J. The stratigraphic position and the con- 

 tained fossils leave little or no doubt as to the corredlness of the 

 correlation. 



The discovery of this fossiliferous outcrop and that at Little 

 Falls makes it probable that further search will bring to light 

 other interesting localities.

JThe Point Levis fossils ( from Point Levis, opposite the city of Que- 

 bec) were described by Billings in the Can. Nat. and Geol., vols. 4, 5 and 

 6, and in Pal. Fos., vol. i, 1861-5; the Calciferous from Rockdale, Duchess 

 Co., N. Y., by Dwight in the Am. Jour. Sci., 3rd ser., vol. 27. 



Note. — Clarke and Shuchert suggest the name Beekmantown for 

 this stage. The reason for this change is "to remedy the present incon- 

 gruity in the nomenclature of the stratigraphic units. As the propriety and 

 necessity of local terms for the designation of such units is generally ac- 

 knowledged, those formations which have hitherto borne names of other 

 significance are now superseded by appropriate geographic names. This 

 formation took its original name from sections in the Mohawk Valley, where 

 the rocks are without fossils. At Beekmantown the normal fauna is finely 

 developed and the rock se<5lion essentially complete.": Am. Geol., vol. 25, 

 No. 2, p. 116.
