Great Britain in the Early Pleistocene Age. 



IN the Pleiocene age the North Sea extended, as we 

 have shown in Fig 10, over a large part of Norfolk and 

 Suffolk. At its close this area was lifted up above the 

 waves, and probably the greater part of it became dry 

 land, over which the early Pleistocene mammalia roamed 

 with complete freedom, leaving their remains in the
