Coeymans limestone 36-114 



A massive dark gray limestone which breaks into 

 very irregular blocks. Fossils are not very plen- 

 tiful and are very difficult to obtain unless the 

 rock has been slightly burned. This formation 

 is not as conspicuous here as it is farther north 

 and the dividing line between it and the shaly 

 [New Scotland] above is not well shown. The 

 fossils are : 



1 Sieberella galeata (Dal.) H. d (7.= Peutamerus galeatus (Dal.) r 



2 Stropbonella piinctiilifera (Con.) H. d C. r

Transitional t)eds ., 12-78 



Limestone which in appearance and fracture is 

 much like the Peutamerus [Coeymans] but 

 which contains a mixture of Peutamerus and 

 Tentaculite faunas^ and is transitional between 

 these two formations. Some of the fossils are : 



1 Leperditia alta (Con.) Hall aa 



2 Spirifer vanuxemi H. r 



3 Pterinea communis H. rr
