226 C* 8. Prosser— Upper Hamilton and 



near the altitude of 1500' and is succeeded by coarse gray 

 sandstone which continues to the top of the hill with an 

 approximate altitude of 1555'. At 1535' is Crandall's flag- 

 stone quarry in coarse gray sandstone. In a cut on the 

 D. L. & W. R. R. less than one-half mile north of the station, 

 and in the quarries along Ransford creek, toward the reservoir 

 northeast of the village, are excellent places for collecting 

 fossils. 



In a small creek about one mile north of Oxford or seven 

 miles southwest of Norwich are exposures of shale containing 

 the same fauna as at Norwich, though this is near the upper 

 part of the zone which soon disappears beneath the surface. 

 On the eastern side of the Chenango valley, at the Lyon 

 Brook Bridge of the O. & W. R. R. is a good section showing 

 the top of the Oneonta zone in the creek below the bridge 

 with the lowest red shales about 150 feet higher, in an old 

 quarry just east of the south approach to the bridge. This 

 section was briefly described by Dr's C. E. Beecher, J. W. Hall 

 and Mr. C. E Hall.* In addition to the species mentioned, 

 the writer found fronds of Archoeopteris in the lower red shale 

 near the railroad bridge, while still higher, in the zone of the 

 Oneonta sandstone in the flrst R. R. cut north of the 218th 

 mile post, are specimens of Amnigenia catsJcillensis (Yan.) 

 Hall, and plates of Holonema rugosa (Claypole) Newb.f 

 Between Oxford and the summit on the O. & W. R. R. and 

 about one-sixth of a mile west of the 214th mile post, is a cut 

 through red and greenish shales in which fossils occur as 

 described in the above mentioned report. One-quarter of a 

 mile east of the Summit in another R. R. cut are greenish and 

 olive shales containing numerous fossils overlying the Oneonta 

 sandstone. 



A similar section may be constructed along the Susquehanna 

 River from Oneonta to Bainbridge. In the Anthony White 

 quarry, at the foot of the high hill just west of Oneonta, are 

 abundant fossils that belong in the " Oneonta group " of Con- 

 rad, which continues up the hill for about 200 feet, the upper 

 portion being composed of the Oneonta sandstone of Yanux- 

 em. The rocks at the base of this hill, or Conrad's " Oneonta 

 group," were correlated quite accurately by Yanuxem, who 

 stated that he supposed them to belong to the " Ithaca group." J 

 Through the kindness of Dr. H. S. Williams I am able to 

 quote from his Ms. list of the fossils collected in the Anthony
