REPORT OF THE STATE PALEONTOLOGIST I9O3 211 



No fossils were noticed 1-2 inches 



D2d Second crinoidal bed. Same character of Hmestone as D2b. 

 The only fossils seen here were Favosites sphaericus 

 Hall which was very abundant, and F. helderbergiae Hall 



which was rare I foot 



D2e Iron stain a line 



The entire Favosites bed is always closed by a line of iron stain. 

 This is not a perfectly straig-ht line but will at times rise a half foot 

 above a Favosites head. The succeeding bed is very full of speci- 

 mens of Gypidula galeata resting often immediately on the 

 iron stain but never, as far as noticed, occurring below this. Speci- 

 mens of Favosites occur in the higher beds, but very rarely as com- 

 pared with their abundance in the Favosites bed. The line where 

 the iron stain occurs weathers into an open seam. 



D3 This bed succeeds the iron stain and but for the very great 

 number of individuals of Gypidula galeata present would 

 have been placed in the upper band of the Favosites bed. This 

 stratum becomes gradually more finely crystalline till the charac- 

 teristic rock of bed D4 occurs. Coeymans 1-6 inches

D4 Very finely crystalline limestone. Few fossils and these mostly 

 specimens of Gypidula galeata. Coeymans . . 21^-3 feet 



D5 Limestone, very coarsely crystalline from the abundance of 

 crinoid joints and broken shells present. The lower portion is 

 specially full of individuals of Gypidula galeata. Coey- 

 mans 4}i feet
