The lowest beds exposed at this section in ordinary 
quarrying operations are the deposits of Bradfordensis 
and Murchisonse hemerae. The earlier deposits were 
proved by excavations undertaken by Messrs. Buckman 
and Wilson. The Sonninise beds exhibit a planed-off top 
with Lithodomus borings, and beds of the Lower Parkin- 
soni zone (“ Garantianse hemera ”) rest non-sequentially on 
them. The gap is partly filled by some strata met with in 
a section to be described presently. 
The next section is taken from the large quarry near the 
church (the Building Stone Quarry).
