The citation for this site states that the cliffs expose many invertebrate fossils from the early PleistoceneRed Crag Formation, and it is the type site for the Waltonian, the first British stage of the Pleistocene.[1][6] However, some authorities date the Red Crag and the Waltonian to the Piacenzian, the last stage of the preceding Pliocene.[7][8]
The site is also significant for its Eocene (56 to 34 million years ago) plant and avian fossils, and it is described by Natural England as "of considerable importance in the study of bird evolution".[1]
The beach below the cliff is open to the public.
