SUMMARY To supplement the recent documentation of the stratigraphy of the Ferriby, Welton, Burnham and Flamborough Chalk formations by Whitham, a study of the nannofloras of this region was undertaken, allowing correlation between the lithostratigraphical units, the macrofossil zones and the recently revised standard nannofossil zonation scheme for the Upper Cretaceous. Attention is draw to the sequence of integrated nannofossil and macrofossil events around the stage boundaries, and some preliminary comparisons of the nannofossil events are made with those of southern England and northern Germany. It is suggested that further biostratigraphical work needs to be carried out through the Cenomanian/Turonian boundary interval, in order to determine the precise relationship between the nannofossil events and the boundary event. The view that the nannofossil Marthasterites furcatus is a suitable marker for the Turonian/Coniacian boundary is reiterated as being erroneous. Documentation of the nannofloras of NE England have proved them to have been influenced by a northern high-latitude (boreal) palaeobiogeographical setting during the Late Cretaceous.
