GREAT OOLITE : DEDDINGTON. 
337 
These beds recall the White Limestones, which are so well 
seen in the country near Glympton to the south-west. 
The lower beds of the Great Oolite in this region, were shown 
in a quarry at North Aston, east of the " Fox and Crown." The 
section was as follows : 
FT. IN. 
Hard imperfectly oolitic and sandy 
limestone ; even-bedded and some- 
what shelly - .-06 
False-bedded rotten marly and 
slightly oolitic limestone and 
marls : with Gasteropods and 
Lamellibranchs, Ostrea Sowerbyi, 
&c. 50 
Hard brown shelly and oolitic lime- 
stones (like Forest Marble) 
Great Oolite -< Marly bed with numerous Lamelli- 
branchs, Trigonia. &c. - 1 
Tough impure and Tery shelly lime- 
stone merging into beds below - 1 
Massive beds of tough brown oolitic 
and shelly limestone (blue-hearted), 
with an impersistent bed of soft 
white or cream coloured earthy lime- 
stone - - - - - 4 
False-bedded hard brown ferruginous 
sandy and oolitic limestone - - 1 6 
Below these beds there occur a layer of black clay, and then sand and 
ironstone of Inferior Oolite age, according to Mr. Beesley, and Mr. E. A. 
Walford. 
The general aspect of these beds, and especially of the lower 
strata, is not unlike beds of the Inferior Oolite (Chipping Norton 
Limestone) ; but the evidence tends to show that only Great 
Oolite is exposed. From the lowest beds of limestone seen in the 
quarry Mr. Walford obtained Nerincea Eudesi, Ceritella parvula, 
Cerithium costigerum and other fossils of Great Oolite character. 
From the upper beds he obtained Cyprina loweana, Trigonia 
costata, Modiola gibbosa, &c.* ; and I have found Cypricardia 
caudata and Thracia curtansata ? It is possible that some of the 
fossils recorded by Mr. T. R. Polwhele from near Deddington, 
may have been obtained from this locality.f 
The further consideration of the Great Oolite is postponed 
until after the Forest Marble has been described ; for in the area 
to the north-east other subdivisions of the Great Oolite Series are 
recognized, and they are best treated together.
