REPORT OF THE STATE PALEONTOLOGIST I903 193 



the most abundant fossils are Atrypa reticularis, 

 Spirifer macrns, Reticiilaria finibriata, Pha- 

 c o p s r a n a and C h o n e t e s h e m i s p h e r i c u s . Above 

 ' this the rock becomies a heavy limestone with thin shale seams at 

 intervals. There are thus over 200 feet of the Onondaga laid down 

 j before the formation becomes the typical heavy bedded limestone 

 i usually associated with this formation. In the uppermost portion 

 ' chert bands make their appearance. This chert is so thoroughly 

 mixed through the limestone that it has when weathered an exceed- 

 j ingly rough appearance. Two hundred and thirty-five feet of the 

 ■ Onondaga is estimated to be here exposed. White^ gives a thick- 

 ness of 250 feet for Port Jervis. For a detailed discussion see K 14 

 I to K 23.
