HUDSON RIVER BEDS NEAR ALBANY 543^ 



Station 32. Eensselaer 



The next fossils were found in a small road metal pit at the 

 corner of High street and Third avenue in Rensselaer (Green- 

 bush) (station 32), where dark glazed shales and eome thin gritty 

 bands are exposed. In the shales were found some specimens 

 of L e p t g r a p t u s e u ib t e n u i s and the young of a D i d y * 

 m o g r a p t u s. The Leptograptus subtenuis isi 

 fiufficient to characterize these shales as belonging to the lower 

 Dicellograptus zone. 



Station 33. Kenwood (Normans kill) 



In the latitude of this station the lower Dicellograptus zone ha» 

 crosised the Hudson river; for 3 miles southwest of it Hall's classi- 

 cal graptolite locality at the lower Normans kill (Kenwood) i» 

 situated (station 33). The rooks, exposed in a railroad cut and at 

 the falls of the Normans kill consist of thick, partly coarse sand- 

 stone banks with intercalated, glazed, grayish argillaceous 

 shales and some black shale from which the graptolites were ob- 

 tained (described in Pal. N. Y., v. 1 and 3). 



Station 34. Glenmont (the Abbey) 



Another locality which furnished fine material and still con- 

 tains graptolites is the cut on the West Shore railroad, half a 

 mile below the station of Glenmont (the Abbey, station 34), where 

 similar beds with a thin black band, full of characteristic and 

 finely preserved Normans kill graptolites, have been exposed. 

 Southward from here, localities with this fauna have been found 

 on both sides of the Hudson river; on the west side as far as 70 

 miles south of Albany (27). 



Station 35. Moordener kill, Castleton 



There is first the fine exposure of '^ Hudson river shales " and 

 of the overthrust Cambrian beds along the Moordener kill or Mur- 

 der creek extending from Castleton on the Hudson, 7 miles south 

 of Eensselaer, to Eiast Schodack (station 35). The section begins 

 opposite the mill of the Fort Orange paper co. with much con-
