J. Jeremiah, A PROPOSED ALBIAN TO LOWER CENOMANIAN NANNOFOSSIL BIOZONATION FOR ENGLAND AND THE NORTH-SEA BASIN, Journal of micropalaeontology, 15, 1996, pp. 97-129
Analysis of abundant, diverse and well-preserved Albian nannofloral as
semblages 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. n
ov., Staurolithites canthus sp. nov., Bownia glabra sp, nov. and Calcu
lites percernis sp. nov. are described.
