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 gomphothere mastodont, otter and vole. Both sites are nationally important for understanding early Pleistocene environments and faunal changes in Britain. Bramerton Common Pit is adjacent to Bramerton Common near Woods End and Blakes Pit is further east at the end of Hill House Road. There is public access to the site.
