Analysis of abundant, diverse and well-preserved Albian nannofloral assemblages from onshore English sections has enabled a high-resolution nannofloral zonation to be developed with the construction of sixteen zones. The results are correlated with the ammonite zonation.Five new species, Acaenolithus viriosus sp. nov., Staurolithites rotatus sp. nov., Staurolithites canthus sp. nov., Bownia glabra sp. nov. and Calculites percernis sp. nov. are described.
