GREAT OOLITE : KIETLINGTON. 323 
between Forest Marble and Great Oolite. The section was not 
deep enough to prove the point ; and it is quite possible that the 
top bed of Great Oolite, west of the railway, has expanded in 
thickness; greenish marly and racy clay was, however, shown 
above the stone-beds in an old quarry a little east of Bletchington 
railway-station, and the evidence thus tends to prove that the 
Forest Marble rests on different members of the Great Oolite. 
Near Islip the Great Oolite has been exposed at the base ; of 
the Forest Marble in several faulted and inlying tracts* (see p. 376). 
The beds consist of pale and more or less oolitic limestones and 
marls, and are much false-bedded in places. 
The first specimens of Gctivsaurus from near Enslow Bridge, 
were obtained from the railway-cuttings, in 1848, by Strickland f : 
and these included a femur 4 ft. 3 in. long. Twenty years later 
Phillips obtained other remains of this huge saurian, to which 
the name Cetiosaurus oxoniensis was given ; and among the 
remains, a femur measuring 5ft. 4 in. in length, was familiarly 
known as the " magnum bonum " of Phillips. He has fully 
described these, and also other specimens from Glympton and 
Chipping Norton. In reference to the remains from Kirtlington, 
Phillips notes that the bones "have been drifted, yet not so 
much as to have suffered by attrition." He adds, that " they lie 
in, or rather appear to constitute, a bone-bed, whose basis is clay, 
with abundance of carbonaceous matter and small masses of wood. ' 
The bed is evidently, that noted as greenish-grey clay, in the 
sections at Enslow Bridge and Bletchington (Kirtlington) ; and it 
has yielded also Avicula, Astarte, Ostrea Soiverbyi, and Terebra- 
tula maxillata. 
Prof. Prestwich remarks that bones are found at different 
levels. He obtained a bone of Cetiosaurus within two feet of the 
Cornbrash, and he thinks that the immense femur (before men- 
tioned) should be assigned to the base of the Forest Marble. 
Bemains of Tcleosaurus were obtained at Enslow Bridge (south 
of Kirtlington) a little below the Terebratula-bed ; and also at 
Kidlington. As remarked by Phillips, the heads of this Saurian 
are found in beds below those containing the large bones of 
Cetiosaurus. Many other fossils have been obtained from the 
Great Oolite of this area, including Ammonites subcontracts : and 
& list, on the authority of J. F. Whiteaves, has been published. J 
To the north-west of Woodstock, a large area is occupied by 
the Great Oolite, as previously mentioned (p. 319). There are 
sections here and there to the south of Ditchley Park, nt Wootton, 
^Kiddington, west of Steeple Barton and Maiden Bower ; and ' the 
pits show white limestones, oolites and marls, which in places are 
very fossiliferous. (See Fig. 91, and p. 163.)
