and Blakes Pit is the type site of the Bramertonian Stage. Both pits have yielded rich, mainly marine vertebrate fossils. The geological deposits include sands, silts and gravels which have yielded fossils of marine and non-marine mollusca, foraminifera and vertebrates. Studies of fossils from Blake's Pit have demonstrated changes from temperate (Bramertonian) to cold (Pre-Pastonian) climatic conditions. Bramerton Common Pit has yielded a rich fossil vertebrate fauna including marine fishes and extinct species of
