The occurrence of Waldheimia digona is of interest, as it is not 
often found in this region, the only other locality noted, being that 
of Wollaston, further east. It would seem that in this country, as 
near Oxford and Cirencester, we have occasional evidence of beds 
that represent the Bradford Clay.

There are several quarries at Moulton Park, near Kingsthorpe : 
that at the lime-kiln on the east side of the road ia as follows :

The Jubs beds make the strongest lime, but the Pavingstone yields the 
best lime for agricultural purposes. The Pavingstone-bed was formerly 
sawn up and used for hearthstones, flues, flooring, window-sills, chimney- 
pieces, &c.* 
Morris noted the occurrence of Pholadomya in these beds in the 
position of lifet; as I have noted also near Roade. The fossils 
from the Great Oolite include Strophodus, Nautilus, Trigonia, 
Cypricardia, Modiola imbricata, Perna, Pholadomya, Pinna, 
Rhynchonella concinna, Clypeus and Crustacea, 
One of the best sections of the Great Oolite and Inferior Oolite 
Series has been exposed at the Ironstone-workings at Finedon.
