Drift Bowlders from the Shore at Tottenville 1 



By- Arthur Hollick 



These specimens were all collected in about three hours' time 

 without special search, on about 150 feet of the beach at the 

 base of the bluff at Tottenville, fronting Raritan Bay. This 

 bluff and the one at Princes Bay are two of the most interesting 

 Drift deposits on Staten Island, by reason of the large variety 

 of bowlders which may be found there. These particular speci- 

 mens represent fossiliferous rocks of five geologic periods (Ordo- 

 vician, Silurian, Devonian, Triassic, and Cretaceous) and at 

 least ten distinct geologic horizons. Some of the fossils are 

 species that we have found before, but others are additions to 

 our previously published lists of Drift fossils. The additions 

 are designated by asterisks (*).
