Description
Area, 0.9 ha. 2.2 ac. Description This classic site and its Silurian rocks were first studied and later described almost one hundred and seventy years ago. It shows fossiliferous Llandovery sediments overlying an andesitic lava flow, the 'trap' of earlier writers. The fauna of the limestones above the lava indicates a late Llandovery age and allows a date to be placed on volcanicity locally, which may be compared with volcanic events in the Mendips and Pembrokeshire at about this time. The fauna is a rich one and includes many species of invertebrates including corals, brachiopods, trilobites, bryozoa and gastropods. This is a key site for regional interpretations of early Silurian faunas, sedimentation and volcanicity.
