This is an important locality for study of the Inferior Oolite limestones, of Middle Jurassic age, laid down in a warm shallow sea some 175 million years ago. The site is unique in that the limestones seen here are much more closely comparable with rocks of similar age found in the Cotswolds than with rock sequences seen elsewhere in Somerset.
This area is significant for studying the Inferior Oolite limestones, which are Middle Jurassic in age and were deposited in a warm shallow sea 175 million years ago. The site's importance stems from its resemblance to limestone formations from the Cotswolds of the same age compared to other rock sequences found elsewhere in Somerset.
