FOSSILS IN THE BOULDER-CLAY OF KINGS COUNTY HAYCOCK. 377 



Pereau river, a fragment of a very fine-grained, laminated, 

 reddish-brown, calcareous shale was noticed on the beach which 

 when broken open was found to contain beautifully preserved 

 impressions of small shells that suggested the small bivalve 

 Crustacea usually known as ostracods. The origin of the frag- 

 ments was for some time in doubt. Careful search of the north- 

 dipping beds in the immediate vicinity failed to reveal it, but 

 several other fragments of the same material, some of which 

 contained fossils, were found within a mile or two of the place 

 where the first piece of shale was found. 



The surface of the red sandstone is here surmounted by a 

 rather thick coating of boulder-clay. About midway between 

 Kingsport point and Pereau river this sheet descends to near 

 the level of the beach, and is well exposed and accessible to 

 examination where a small brook meets the shore. A brief 

 search in this formation brought to light a glaciated fragment 

 of the same material, which when broken open revealed the same 

 fossils and the problem of the immediate origin was solved. 



The location of the strata from which these fragments were 

 detached by the ice of the Glacial Period has not been fixed as 

 yet. The striation of the bed-rock in this county, and the 

 presence of arnygdaloidal trap from the North Mountain in the 

 boulder-clay, indicate that the ice moved and brought its load of 

 clay and stones from the northwest. The source of these frag- 

 ments must also be to the northwest, but in that direction the 

 Triassic red sandstone extends to the trap of the North Moun- 

 tain. Beyond the trap, on the very shore of the Bay. is a newer 

 formation of greenish calcareous shale ; but a careful study of 

 every exposed section of these newer beds has revealed no layers 

 in any respect resembling the fragments in color, composition or 

 fossil contents, and there is no evidence that they were derived 

 from that formation. That they were derived from beds on the 

 Cumberland shore, the more distant New Brunswick coast or 

 the bottom of the Bay of Fundy is also unlikely, so that we 

 must look to the Triassic beds intervening between the Kings- 

 port shore and the North Mountain as the source of the frag- 

 ments.
