Description
Description Grimston Warren Pit is a small disused quarry located approximately three kilometres eastnorth east of King’s Lynn. The quarry provides an outstanding opportunity to examine the constituent facies of the Dersingham Formation, a sequence of yellow to rusty coloured clay rich sands. Beneath these are clean white sands assigned to the Sandringham Formation Leziate Beds. The Dersingham sands are particularly important as they have yielded the ammonite Endemoceras which indicates an Early Cretaceous Hauterivian age. Grimston Warren Pit is a nationally important site for dating the constituent facies of the Lower Cretaceous in north Norfolk and for elucidating the palaeoenvironmental conditions which existed during Hauterivian times.
