A quarry known to local geologists as the Forest Marble Pit, 
on the hill north of Lower Tadmarton, affords evidence of the 
junction of Great Oolite and Forest Marble with a very irregular 
line of demarcation. The section was as follows : 
Forest Marble 
Great Oolite 
f Stiff brown and stony clay, resting in 
" pipes " on bed below 
Thin reddish-brown shelly limestones - 
Grey shelly marl 
Fissile shelly oolite (blue-hearted) 
Hard compact grey limestone, with 
Modiola ... 
Brown and pale-grey flaggy shelly and 
earthy limestone, with Ostrea, &c. -

According to Mr. Beesley the oolite at the base has been 
quarried to a depth of 10 feet. He notes that remains of 
Teleosaurus were obtained from the Great Oolite of this 
quarry.* The compact grey limestone here taken as the top 
of the Great Oolite, appears to correspond with that at Swal- 
cliffe (p. 334) ; but correlation is hazardous. 
A somewhat similar section was exposed at the lime-kiln north 
of the Fulling Mill, west of Broughton. There I obtained Ostrea 
costata and O. subrugulosa from the clays overlying the Great 
Oolite; and from the Great Oolite, Natica, Cardium, and 
Pholadomya ', Mr. Beesley notes other fossils. 
At the Tadmarton Lime-kiln, lower beds of Great Oolite are 
worked to the depth of about 12 feet. They comprise pale earthy 
and slightly oolitic limestones, and hard and soft marls, resting 
on a hard blue-hearted shelly oolitic limestone, and covered by a
