12 FAUNA OF THE CORNBRASH. 



Weymouth. The various members of the Cornbrash are seen scattered about the 

 neighbourhood, but their position relatively to the above can only be determined 

 by the fossils. Thus there are two quarries on the roads leading from Driffield 

 Cross to S. Cerney ; that on the northern road is probably high in the sequence as 

 containing a species of Ammonite, that on the south may be lower as containing a 

 Nautilus. 



1-5. Fairford to Woodstock. — In all this flat country the Cornbrash appears to 

 be reduced to its minimum, and forms a mere surface capping exposed in a series 

 of shallow openings, and the fossils are principally composed of the larger and 

 rougher sorts. Some of these shallow openings may be seen : between Fairford 

 and Hathrop, between Fairford and Southrop, east of Southrop, and on Curbridge 

 Down. It forms a capping only to lower strata in quarries at Alvescott, at the 

 cross-road west of Shield Farm, at the side of the Woodstock Road near Whitney, 

 probably the locality of Horton's fossils (see p. 10, No. 27), and in the railway line 

 at Handborough. The coral bed of Fairford has already been proved to belong- 

 to the Great Oolite (see Woodward, op. cit., p. 296). 



16. At SmrTON-ON-CHERWELi. on the Woodstock Branch Railway, east of the 

 Banbury Road, is seen a complete section from the Oxford Clay to the Forest 

 Marble Clay, of which the following description is given by H. B. Woodward 

 (op. cit., p. 44) : 



Ft. in. 



1. Rubbly and fissile marly limestone, with lignite, Waldheimia lagenalis 1 



2. Impure limestones, with lignite, etc. . . . . .12 



3. Hani mottled limestones, Waldheimia lagenalis . . .16 



4. Soft earthy and shelly marl and mottled blue and grey limestone, Avicula 



echinata, etc. . . . . . . .40 



5. Hard bluish limestones with marly patches, Avicula echinata, etc. . .20 



6. Fissile marly beds and tough brown and grey shelly limestone, with Avicula 



echinata and Terebratula intermedia . . . . .20 



Forest Marble Clay, 6 feet, etc. 



The horizon of fossils obtained from the spoil-heaps when the railway was 

 being made can only be judged from the matrix, which leaves in some cases room 

 for error. Macrocephalites has been recorded from this section, but not from any 

 definite position. 



17. Kidlington, Kirklington, AND Tslit. — The exposure known as Kidlington 

 is a now deserted pit by the side of a- field path branching off to the north from 

 the road leading from flic village to flic station. Many fossils have been recorded 

 thence and may still be found. Woodward's section may still be seen : 



Ft. in. 



1. Rubbly limestone, with Avicula echinata . . . .40 



2. Grey racy clay . . . . . .08 



3. Rubbly limestone, with Terebratula in the lower pari . . .30
