Ransley Quarry is a key geological site in South Devon.
Ransley Quarry exposes the upper levels of the East Ogwell Limestone (Givetian-Frasnian) which comprises a bioherm (‘reef’) of massive limestone draped with shales and shaley limestones. This has yielded a rich and varied fossil fauna. The lithologies associated with this biohermal development at Ransley (forming part of the local East Hill succession) differ from the other East Ogwell Limestone exposures. This site exposes the best example of a Frasnian bioherm known in Britain.
