30 ANIMALS OF THE SEASHORE 



There was less water in the sea than at present 

 because immense quantities of water were locked up 

 in the land ice. The shore line of New Jersey conse- 

 quently extended far beyond its present position. 

 For instance, the site of Atlantic City would have 

 been some 75 miles from the sea ! Fossils laid down 

 in this glacial sea would have been deposited far 

 from the present shore line and would consequently 

 seldom be found on the beach except when they were 

 carried by unusually heavy seas. 



The following species, at present only living' north 

 of New Jersey, probably lived in this glacial sea: 

 Buccinum wndatum, Neptunea decemcostata and CoIuh 

 gracilis. Neptunea si one 'i, an extinct gastropod of 

 northern affinities, probably also is a shell of this 

 glacial sea. All these species are very rare on the 

 New Jersey beaches.
