Microvertebrate fauna

Despite the formation being nearly entirely marine, at several localities abundant remains of terrestrial microvertebrates are found, the primary locality being the Kirtlington Mammal Bed (designated 3p) near Kirtlington, Oxfordshire.^[16] Another important locality is Watton Cliff in Dorset.^[17]
