1. Gravel pit near Mr. Lyons house which
shows false bedded chalky gravel containing sub-angular fragments of flint,
oolitic limestone & argillaceous limestone. The flint being most rounded.
Contains also
Gryphaea arcuata,
belemnites,
Ostrea.
False bedding due to current from West. Remains of
Elephas
primigenous (mammoth) have been found here.
No.2.
Another small pit
near road – is oolitic limestone; one band which is full of fossils – 3 feet
exposed. It is flaggy thin, irregular bedded, yellow, soft oolitic limestone
with numerous fossils –
Terebratula (maxillata),
Rhynchonella,
Trigonia,
Pinna,
Modiola,
Pecten ?
corbula ?,
Myacites. This
from its position evidently underlies the gravel pit. Dip N 70 degrees E, amount
5 degrees.
