Whicher J., Chandler R. (2009) Inferior Oolite (Middle Jurassic) hardgrounds and the associated faunas at Coombe Quarry, Mapperton, near Beaminster, Dorset // Proceedings of the Dorset Natural History and Archaeological Society. V.130. P.149–153. Pdf: http://rogov.zwz.ru/Whicher....%29.pdf
Coombe Quarry near Beaminster exposes an example of the incomplete succession of Inferior Oolite rocks that typifies South Dorset. There are two large non-sequences within the succession, one in the Lower and one in the Middle Inferior Oolite, that are marked by distinct hardgrounds. These show different features that can be related to their contrasting mode of formation. The first occurrence of Gastrochaenolites lapidicus within the Inferior Oolite of Dorset is recorded.
