Recent examination of the well-known Shenley Hill Limestone lenticles and of the Regularis Nodules of Billington Crossing has resulted in the discovery of a number of new records. It will be remembered that Lamplugh and Walker in 1903 (1) and Lamplugh again in 1922 (2) placed the Shenley Hill Limestone at the top of the Lower Greensand both on stratigraphical and palaeontological grounds.
