 FOSSILS. 



FIG. 245. 



This rock is very barren in fossils, and those found are very obscure. First we will mention the plants. 



These are all fucoids. The most distinct 

 among them is figured in outline in Fig. 245, 

 reduced to one-half the natural size. It ap- 

 pears to be related to the Fucoides chemung- 

 ensis, figured by Prof. Hall from the Chemung 

 group. The specific diiferences are not great, 

 but the fact that it occurs in an entirely dis- 

 tinct group of rocks is probable evidence that 

 it is a distinct species. 



There are one or two smaller species of this 

 genus which are not represented in any fig- 

 ures, but are to be found in the State Cabinet 

 with the other fossils of this group. 



The localities of the first species (Fig. 245) 

 are in Addison, Bridport, and probably along 

 the whole range of the western belt of. the se- 

 ries; but they are developed unusually well at 

 Shelburne, an eighth of a mile north of the

depot, on the road to Burlington. There the 

 smaller species also occur. At Willard's 



Ledge, in Burlington, there are some similar fucoids, which were regarded as ichnoid impressions by Prof. 



Adams. Fig. 246 represents them, as drawn by Prof. Adams.
