1913 AMMONITES BRAIKENRIDGII 8ic 



Geological position : The Ironshot Oolite of Dundry is the highest 

 bed of Bajocian preserved in the hill : the matrix is most distinctive. 



Although this species is not a Yorkshire type, yet as Am. braiken- 

 ridgii luis been claimed as a Yorkshire species (Morris & Lycett, 1850, 

 1, p. in) it is important to prove that the claim was not justified 

 (See S. Buckman in Richardson, 191 1, 205).
