NOTE 



ON THE OCCURRENCE OF " ROSTROCARINATE " 

 IMPLEMENTS IN GUERNSEY. 



BY ME. A. COLLENETTE. 

 READ ON 18th OCTOBER, 1916. 



The members of the Society will remember the fact that 

 Mr. J. Reid Moir, described flint implements possessing a 

 curved base to which he gave the name " rostrocarinate," in 

 the crags beneath the Norwich glacial drift. 



Dr. Marett, of Jersey, reports one of the same shape as 

 occurring in the Mousterian Cave (Cotte de St. Brelade). 

 He says a specimen of " rostrocarinate " form possibly a 

 mere " outil de fortune." 



Having in the museum two such shapes, and having 

 received two more recently from Mr. Morgan, I think it is of 

 interest to make a record of the fact. I show the four 

 museum specimens. Nos. 1 and 4 are from Mr. Morgan, 

 No. 2 is from LTslet and No. 3 from L'Ancresse. 



As the two last named places have had a deposit of 

 glacial clay over them nnd Mr. Morgan's ground is entirely 

 derived from such clay, it is reasonable to suppose that they 

 are the work of the same period. 



The form must, if we give full weight to Mr. Moir's 

 implement, be a very old form, but the find in the Jersey cave 

 points to its use by Mousterian Man and we are finding ours 

 in the same horizon. 



It is not difficult to imagine that the art of striking such 

 flint from cores derived from conchoidal flints may have been 

 easily acquired even at the earliest flint age, and we know 

 that flat bases could be struck at will from suitable cores.
