The zonal position of the Gault-Lower Greensand junction beds at Wrecclesham, Surrey

Abstract

Re-opening of old workings at Wrecclesham, Surrey, has permitted a detailed examination of the beds at the junction of the Gault and Lower Greensand and has led to the discovery of a highly interesting ammonite fauna, assignable to horizons within the Tardefurcata Zone (Lower Albian) and the Mammillatum Zone (Middle Albian). This provides the first record of the Tardefurcata Zone in Surrey.
