INFERIOR OOLITE SERIES : DOULTINQ. 
.37 
o 

Upper Division. 
Zone of 
Ammonites 
Pavkinsoni. 
Beds presenting these characters were exposed at Hedgestock 
Quarry, E.N.E. of Creech Hill ; and in a quarry, further south, 
en the road to Brut on. Fossils are exceedingly scarce : an occa- 
sional Terebratula, Trigonia or Coral being the only specimens 
noticed. 
On Creech Hill the beds are somewhat different in character 
and more fossiliferous. The following section was exposed in the 
quarries and cuttings :

Eeddish-brown brash y s;>il. 
Pale oolite much broken up and 
lime - washed. Rhynchonella

Rhynchonella spinosa is here found in almost the lowest bed of 
the Inferior Oolite : but ns it occurs in the zone of A. hum- 
phriesianus it is quite possible that that zone may be represented 
in the Upper Division, as well as the zone of A. Parkinsoni. 
De la Beche has estimated the thickness of the Inferior Oolite 
to be 55 feet;, and of the underlying Sands, 66 feet, at Scale Hill, 
Bruton.* Our information concerning the lower beds of the 
Inferior Oolite in this region is very scanty. From the Sands at 
Cranmore Mr. Hudleston obtained a specimen of Ammonites 
fallaciosus.\ 
The Doulting Stone, which for many centuries has been worked 
north of Doulting village, and eastwards towards West Cran- 
more, is considered a very durable stone. The beds seen are 
exceedingly variable, being false-bedded on a large scale and 
minutely current-bedded : and it is difficult to correlate the layers 
seen in different quarries. 
The general sequence of beds was shown in the railway-cutting 
where the section was noted in 1863 by Messrs. W. A. E. 
Ussher, J. H. Blake, and myself.J When I again visited the

marked 200 instead of 20 feet.
