In many parts of the UK, the rock of the ‘Corallian Group’ is rich with fossil corals. But that isn’t the case in Dorset. Only the Ringstead Coral Bed contains corals in significant numbers. That is because, for most of the time during which the Corallian rocks were forming, the environments in what we now call Dorset had too much sediment for corals to survive.
