The similarity between the fossils of this group and those of the Great Oolite is 

 very remarkable ; many Minchinhampton fossils occur in it which, as yet, I have been 

 unable to detect in the Great Oolite of this district. Teeth of fishes, which are so 

 abundant in the Wiltshire Forest Marble, appear to be somewhat rare in the same 

 beds in Oxfordshire. The Cornbrash at Islip and Kidlington has yielded the following 

 assemblage. 



Cidaris Bradfordiensis, Wr. (plates and

A careful study of the fossils of the Oxfordshire Cornbrash appears to me by no 

 means favourable to that theory of Professor Buckman, that the Cornbrash assemblage 

 of fossils, on the whole, more strongly resembles the fauna of the Inferior than that of 

 the Great Oolite.
