358 LOWER OOLITIC ROCKS OP ENGLAND: 
from the Forest Marble. Above the Bradford Clay at West 
Keynton we find beds of fissile and false-bedded oolite, resembling 
Great Oolite, but on the west and north-west side of the village, 
there are shallow quarries showing 4 or 5 feet of fissile shelly 
limestone and oolite, with ochreous galls and layers of grey clay. 
These beds yield crushed specimens of Rhynchonella, also Tere- 
bratula maxiilata, Ostrea lingulata, Pecten vagavs, spines of 
Echini, and joints of Apiocrinus. Northwards the Forest Marble 
occupies an extensive area around Badminton, on the dip-slope of 
he Cotteswold Hills. 
Near Castle Combe and Yatton Keynell the stone-beds are 
-very variable in character. To the west of Giddy Hall, we find 
false-bedded sandy and oolitic beds, quarried to a depth of about 
16 feet, with 6 feet of grey clay at the base ; and east of Castle 
Combe we find the oolitic and sandy beds surmounted by yellow 
sand and fissile calcareous sandstone, like the Hinton beds. 
The highest beds of the Forest Marble were exposed south of 
Lower Stanton, near Stanton St. Quintin, where beneath the 
Cornbrash there occur blue clays with thin gritty layers, exhi- 
biting the peculiar trails or tracks so characteristic of the Forest 
Marble. The evidence of this succession is confirmed by a 
section at Kington Bottom, near Kington St. Michael, recorded 
as follows, by Lonsdale* :

Near Malmesbury we find a considerable development of the 
sandy beds. A cutting by the railway-station showed thick beds 
of flaggy and concretionary sandstone, together with oolitic shelly 
limestones and white sands, resting on about 20 feet of flaggy 
calcareous grits and shales, the former showing ripple-marks and 
trails. On the road to Tetbury, north of Broken borough, there 
is a large quarry showing the following beds :

of gritty limestone, and occasionally 
thicker irregular bands of calcareous 
Forest Marble-^ sandstone - - - 10 
I False-bedded oolitic limestones, with 
much lignite, rotten ochreous galls, 
L and partings of ochreous clay - 12 
The beds appear to rest on clay, as shown by the water held up 
at the bottom of the quarry. Fossils may be obtained, including 
Pecten annulatus, Ostrea Soicerbyi, Rhynchonella^ &c. In this 
neighbourhood, and probably at this quarry, the Crab Palceinachus 
longipes was obtained by William Buy, and afterwards described 
by Dr. Henry Woodward.f
