Portland Cement Co. Quarry, Beggar's Knoll (Cretaceous of the United Kingdom)

Where: England, United Kingdom (51.3° N, 2.2° W: paleocoordinates 40.9° N, 0.2° W)

• coordinate estimated from map

• local area-level geographic resolution

When: Lewes Nodular Chalk Formation (Chalk Group), Turonian (93.9 - 89.8 Ma)

• The macrofauna found by members of the Bristol University party dates the horizon as probably Turonian, this being later confirmed by the identification of the microfauna.

• formation-level stratigraphic resolution

Environment/lithology: marine; lithified chalk

• The chalk exposed here, both on the face and in shattered blocks is greyish-white, and sometimes nodular: the nodules are occasionally green on the surface. Two minor bands on flint are also visible in the quarry face

Size class: macrofossils

Collected in 6th March 1963

Collection methods: bulk,

• Specimens retained at University of Bristol, Geological Museum.
