GREAT OOLITE : M1NCHINHAMPTON. 
277 
Great Oolite 
(Upper Division). <( 
Kemble Beds. 
The beds, which, exhibit a gentle anticline, dip at about 2 towards the 
north-west and south-east. The higher beds (above the shivery freestone) 
are tolerably even layers, though wedge-shaped in places. 
South-east of the railway-bridge there is a fault that brings on higher 
fissile beds of gritty limestone and shales, that belong to the Forest 
Marble. 
In the cutting by Hayley Farm, south of the small tunnel, and 
in that between the two tunnels, we have the following succession 
of beds : 
FT. IN. 
Bubbly and coarse-grained oolites, with 
marly layer near base ; beds becom- 
ing flaggy near the top - 10 
Hard white pisolitic and oolitic lime- 
stone, with hard nodules near the 
top. Bone of Megalosaurus (?) on 
surface of stone - - 1 6 to 2 
Ochreous marly and sandy parting (im- 
persisteut), with tooth and bones of 
Megalosaurus, and Plant-remains. 
Pisolitic and brecciated oolite - - 1 9 
Clayey seam. 
Compact oolite, with large grains* -12 
Brown and white fossiliferous ooiite - 1 6 
Pale and buff oolites (freestones) - 11 6 
Fine oolitic and pale earthy limestone, 
and rubbly marl, passing into brown 
oolite at base. Fossil Bed : with 
Natica, Nerincea pseudopunctaia ? 
Pleurotomaria, Cypricardia caudata, 
Homomya Vezelayi, Lima impressa, 
Lucina bellona, Myacites, Ostrea 
costata ?, Rhynchonella dbsoleta, Tere- 
bratula maxillata, Echinobrissus 
Woodwardi, &c. ~ - -50 
Remains of Mesodon and Stropkodus were also obtained from 
the beds in this cutting : and the fossils agree generally with 
those obtained from the Upper beds of Great Oolite by College 
Farm, Cirencester. The beds dip at an angle of 2 towards the 
south-east. 
The short cutting between the two tunnels, although it showed 
beds perhaps on a lower horizon than those in the cutting to the 
south, yet it did not exhibit any marked fossil-bed. This, however, 
is not surprising when we know that the fossil-beds (as seen near 
Kemble) end off abruptly. 
Beneath the beds thus recorded in the open sections, adjoining 
the Sapperton railway-tunnels, we have the folloAving account of 
the strata noted by the Engineer, R. P. Brereton, and published 
by J. H. Tauntont : 
FT. L*.
