Rockhall Wood Pit, Sutton is a 5.3-hectare (13-acre) geological Site of Special Scientific Interest west of Shottisham in Suffolk.[1][2] It is a Geological Conservation Review site both for its quaternary and neogene deposits.[3][4]
This site has excellent exposures of the Pliocene Coralline Crag Formation, with a vertical sequence of diagenetic changes and rich fossil fauna. It is described by Natural England as probably the most important Pliocene site in Britain.[5]
This site is private land, but part has been converted by Geo Suffolk into a 'Pliocene Forest', with trees similar to ones which would have grown in Suffolk four million years ago.[6]
