252 LINCOLNSHIRE NATURALISTS’ UNION AT LINCOLN. 
also given by brick pits, is represented by the Marlstone or its 
equivalents, and by the clay beds below, which in places are 
ferruginous with phosphatic nodules and septaria. This series has 
yielded Am. margaritatus, Rhynconellas, Ichthyosaurs, Plesiosaurs, 
fossil wood, etc. The Lower, which can best be seen to the south 
of Lincoln, only appears in small quantities at the base of the cliff, 
from whence it runs in a westerly direction till it meets the Rheetic 
Beds beyond Thorney, at North Scarle, Kettlethorpe, and other 
places. This latter series, though covering so wide a surface area, is 
not easy of access, large tracts of it being covered up by alluvial 
and river deposits, and boulder clay. The Oolite capping at the 
top, which is about 18 feet in thickness, forms part of the Inferior 
Oolite, and is known as the Lincolnshire Limestone, out of which 
the Cathedral is built. Its basement beds can be studied in the 
fields to the east of Lincoln, leading to Greetwell, where hard beds 
of the Northamptonshire Sand are being worked for iron. The 
Inferior Oolite passes into the Great Oolite series at Nettleham and 
other places, the highest beds of which, known as Corbrash, 
abound in fossils, and may be seen on the surface beyond Greetwell, 
and at Sudbrooke, etc. These are followed in due course by the 
Kellaways Rock beds, which crop out at Cherry Willingham and 
other places, and which in turn dip under the Oxford Clay.
