REPORT OF THE STATE PALEONTOLOGIST I903 I93 



the most abundant fossils are Atrypa reticularis, 

 Spirifer macrus, Reticularia fimbriata, Pha- 

 cops ran a and Chonetes hemisphericus. Above 

 this the rock becomes a heavy limestone with thin shale seams at 

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

 before the formation becomes the typical heavy bedded limestone 

 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- 

 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 

 to K 23.
