West of Mere and opposite the opening of the road to Gillingham 
is a quarry that has been worked for some time, and exposes the 
whole series of junction beds, dipping at about 5° to the east. 
This section has been carefully examined by Mr. John Scanes of 
Maiden Bradley, and has been described in a recent paper* from 
which the following account is taken ft. in.

The beds in bracket A belong to the Selbornian, those in the 
bracket B we now regard as belonging to the zone of Ammonites 
varians, while C are surface accumulations. 
The matrix of the “ popple-bed ” is hard, and resembles a sandy 
mortar. The “ popples ” are flattish oval lumps of calcareous stone 
from 2 to 5 inches long. Many of the fossils are well preserved 
and the bed is clearly marked off both from the underlying sand 
and from the sandy marl above. This latter is also hard and 
compact, and though fossils are abundant they are not readily 
released from the matrix. 
The excellent section in the quarry at Maiden Bradley has been 
given in Volume I. of this Memoir, and in the paper above men¬ 
tioned, but particulars of the beds which seem to be referable to the 
Cenomanian may now be given. These have been noted by Mr. 
Scanes, who has repeatedly examined the section, and has collected 
indefatigably from each of the beds disclosed : — ft. in.
