At Foxhole, north of the Cywyn Valley, another good exposure 

 occurs, where some quarrying operations have been carried on within 

 recent years. The character of the beds is very similar to that of 

 those exposed in the lower portion of the section at Llandeilo-aber- 

 Cowyn, and the fossil-assemblage presents the same facies.
